🌸 post-catws stucky + hug

The first tendril of want shocks him like a splash of ice-cold water poured down his spine.

Bucky doesn’t know at first – doesn’t know what, doesn’t know how. But the want is there, curled up in his chest: small, and starving, like some trembling newborn thing whose first taste of life is hunger, crying to be fed and soothed.

There’s a half-remembered feeling in the back of his mind, something he reaches for when the want aches sharp and spark-bright inside him. The word for it is short and sweet in Bucky’s mouth, so gentle it barely touches his tongue at all, all throat and soft palate: ‘hug’.

It’s a simple concept. Two arms go around one body – that’s all it takes. One step, and there it is: a hug. And Bucky imagines it vividly: his own mismatched arms around Steve, and Steve’s arms folding around him, like a circle – the shape of the infinite, of timeless things like the two of them. A line that should end, but constantly finds one more beginning instead.

He tries to see it, Steve’s broad chest brushing against his as their bodies meet, the swell of Steve’s arms enveloping him, Steve’s big palms splayed wide against his back, touching him. Gentle. Like Steve’s eyes on him are gentle; like the clasp of his hand on Bucky’s shoulder is gentle, always. So gentle, perhaps, that Bucky would hardly even feel the hug around him.

But he would take it, gentle or no. Because the truth, where it lies in the empty pit of his stomach, is that he starves for it, day after day, the want pulsing inside him with every beat of his heart. He just doesn’t know how to ask for it.

So Steve does the asking for him.

His hair is ruffled, limned with copper and wisps of gold in the late afternoon light, and his hands are unsure, nervous. But his eyes. His eyes take Bucky in, searching, urgent – and for a moment, Bucky is sure that Steve, too, must have been starving for this.

“Can I hug you?” he says, and the word sounds especially sweet when it’s Steve pronouncing it. When there’s a ‘you’ attached to it, and that one syllable becomes two, joined seamlessly together, and the new word rolls smooth and honeyed down the curl of Steve’s tongue, hug you, hug you, hug you. “Would that be okay?”

Bucky wets his lips. ‘Yes,’ he means to say, but the word that slips out of his mouth in a rasp instead says, “Please.”

So Steve gathers him close, two arms and one body and his nose buried in Bucky’s dark mop of hair, and he carves a snug space out of himself to make room for Bucky right there, his hands fisted in the back of Bucky’s shirt, their chests pressed so tight together that his heartbeat pounds behind Bucky’s ribs.

It’s not a passing touch, the fluttering echo of a hug Bucky feared he might barely feel. It’s persistent. It’s desperate. It’s a hungry little thing, a creature to be fed tenderly, steadily, so it’ll grow and live, and live.

He wraps his own arms around Steve, and grasps at him just as fiercely as his want commands, a wet exhale shuddering out of his lips to land in the crook of Steve’s neck.

He was wrong, he realizes now, framed in Steve’s embrace like a timeless work of art. He was missing a step.

A hug is a simple concept: two arms go around one body, and they hold on.

smallidarity highschool au

came up with this au like actually 2 years ago where it's mainly empires 2 smallidarity centric, with Jimmy as a student council member and Joel as an honours student who doesn't like the way Jimmy runs things around the school.

As payback for the regulations Jimmy put up that Joel thought was stupid, Joel does these elaborate 'The Office' style pranks on Jimmy (specifically) while Jimmy retaliates by trying his best to dig up dirt on Joel. This banter goes on for a while— however Joel ends up doing the pranks less as a statement, and instead more just to see how Jimmy would react... with his comical, cartoony villain yells, and... weirdly cute face....? (YAOI YAOI YAOI YAOI)

very very old au drawings below:

from July 2023

😭😭 joel does NOT look like a highschooler here 😭😭😭😭 (i also wanted to draw angst in the first two ig idk a year later it's pretty cringe [i am still cringe]) (also partially inspired by when I read "Go for it, Nakamura!" and the mc reminded me of joel for no actual reason. or maybe i was just thinking about that manga while drawing smallidarity. idk)

from November 2022:

I think these doodles were genuinely the first instance of me converting from being against mcyt shipping to for shipping LMAOO

[jinhyun]

Omg omg i am convinced that hyunjin takes boyfrie privileges actually pretty seriously. It's so cute. What do you think his response would be if his s/o was someone who's really comfortable w others and likes to loop their arm through whoever's they're walking with/physical connection with their friends in general? Like, they all went out for a fun day and his s/o is walking with like jisung and hyunjin's s/o links arms with jisung as they walk and talk?

"Oh?"

"What?" you wonder.

"Didn't know Han was your boyfriend now".

You amusedly roll your eyes, with one simple look at Han letting him understand the assignment and having him walk ahead of you while you switch to loop your arm around Hyunjin's. "Aw, come on. I always do this with my friends. It's friendly".

"You always do it with me, though" his eyes fix on your linked arms. "You're doing it right now".

"So?"

"I'm your boyfriend," he states, as if it weren't clear enough already. "And this is friendly?"

"Not when it's with you, though" you clarify.

He pouts. In the matter of a couple of seconds, one of the actions he considered to be boyfriend privilege only, had been scratched off the list.

In a matter of seconds, something he considered to be special, was not anymore.

So, he unlinks your arms.

Not missing your touch, however, his hand travels down to lock with yours — the familiar and comforting feel of your fingers intertwining with his immediately sends butterflies flying around his stomach.

This, he's sure is something only he can do with you.

"Don't go around holding hands with anyone else" he mumbles anyway.

You smile, leaning lightly against his body and giving his hand a gentle squeeze right as you press a lingering kiss to his cheek. "Oh, don't worry about it. Holding hands is reserved for my boyfriend only".

And Heaven forbid it was ever not.

Hualian modern poetry AU be like

Hua Cheng has the nastiest handwriting ever so he can write whatever he wants wherever and whenever he wants and nobody will ever understand anything of what he writes so he greatly prefers that over typing stuff

So he goes to the library every day (he's an art student) and sits to this very specific table every day, puts on his headphones and then studies art history taking notes on his notebook writes poetry about the cute librarian whom he can see perfectly from the table he chose (cause he's a mastermind)

And sometimes his poems are like the sweetest, purest thing ever, cause his beloved deserves to be treated like the deity he is-

Other times they gently, ragingly go beyond the nsfw-ness but he doesn't care cause nobody will ever read his poetry irl

But Hua Cheng is a modern simp so of course he has a tumblr blog where he posts his poetry and simps hard anonymously about his beloved and has tons of followers who comment on his works with love and admiration for his skill

And of course Xie Lian is the other big poetry blog in the community but unlike Hua Cheng he writes about pain and hopelessness and nightmares

(until he bumps against someone and Xie Lian's eyes -golden in the sunlight- meet Hua Cheng's mismatched, mesmerising eyes and he doesn't know how to put his words anymore if not to celebrate life and the luck of a chance encounter and its ability to save one's life)

I think, given the chance, Billy would absolutely drag Max to every single concert he went to. Sure it’s fun going to a concert and hooking up with guys or trying to weasel his way into backstage, but it pays off a whole lot more when he sees Max’s eyes go wide the first time she sees Motley Crue play.

When she feels the rumble or drums in her chest and gets her ears filled by shrill sounds of the guitar solo.

And he feels a bit of pride when he sees her mouthing or screaming along to songs she knows because she has heard them so many times in Billy’s car. And he sees the moment it clicks for her that, hey, this is pretty fucking cool.

Before the show, before every show they go to he gets her a patch from that band. Because he knows she won’t hang up the posters and she doesn’t really wear band shirts. So he gets her patches and buttons and maybe she doesn’t put them on anything for a while, because that’s not her style. But she still loves them just the same.

And it reminds her that in the end, Billy will always be there for her. That when the ground gets too rambunctious she can squeeze on his arm and he’ll pull her in front of him. Or if a weirdo is over stepping a boundary he will be the first one to throw a punch. Because at the end of the day, it’s the both of them against the world.

Dead Friend Forever BTS | JJay & Fuaiz as Tee x White

"Tee heard the gunshot and was so worried about White. Then, White opened the door, and we hugged. Inside, I felt the relief.

I'm an absolute sucker for height difference. I love person A hugging person B, and making them look even tinier in the process.

[whumblr]

can you write a prompt for an intimate whumper x whumpee? 😭

"Sshh, it's okay, loved one, it's okay. I know you don't like being touched. That's fine. I don't mind. You're allowed to feel that way. You know, I might even prefer it that way. What you're not allowed to do, however, is pull away from me."

[butmakeitgayblog]

It's not talked about a lot in the fandom but I love how high pitched Lexa's voice is. I know Alycia tried her damned hardest to make it low and intimidating but damn that's the best it can do 😳 she looked hot af as Big Bad HedaTM but the moment she spoke on screen with her unmistakable "oh yeah that's Alycia" voice......... I was a GONER. Like the video of "not everyone, not you" you just posted?? Like somehow I never remember exactly how feminine she sounds when I'm reading fanfics 😂

Because Alycia quite literally was the perfect little delicate bean to play that role 😩

Not to get off subject but like, that's part of why I'd never want a spinoff. No one can play this character but Alycia. No one.

Because I feel like Alycia understood the assignment. In a way a lot of other actors probably wouldn't have, imo. She didn't strain to be something she wasn't or try to add a bunch of vibrato and bass to her voice, because that wasn't the kind of person Lexa was. She could do it to a degree, we see it in the scene when they believe Gus has been poisoned and she commands "No Skaiperson leaves this room!" But even then, filled with anger and fear of losing a confidant and father figure in her life... she still sounds like a young woman who is also just a pissed off leader. Alycia didn't strain to make it gravelier or darker. Because her power in that character doesn't come from false pretenses. She doesn't overtly or heavy handedly try and masculinize herself to convey strength. While I don't think there's anything wrong with that approach by any means, it just isn't always necessary.

And I know there is an argument to be made about them feminizing her even further in s3 for various sexist reasons, I do. But I still appreciated the overall performance and portrayal for what it was because despite all of the show's flaws (which were numerous 😒), letting a powerful woman figure be thoughtlessly and unremarkably feminine while also being a bad bitch just isn't something we see a lot imo. Usually if they're feminine, they're shrinking violets who are just shy and dainty and reserved. Stronger figures tend to be more masculine. More solid. More rigid. Deeper voices. Less feelings.

Lexa, however, was really none of those things when you truly look at her, despite the fact that she was unquestionably a larger than life presence on screen. She beat the shit of men twice her size and stood toe-to-toe with her enemies, commanded armies and led 12 warring nations under her iron fist leadership, she lost everyone she ever cared about and had her heart broken more times than she could count and still she dared to let herself fall in love again. Lexa was strong and she was vulnerable, she was lethal and she loved deeply. She was timeless and just a young woman trying her best to be a leader. Lexa was so many things all at once, and I appreciate the fact that Alycia didn't really bog it down with trying to convey her as something she wasn't.

And she did it all with that sweet dainty voice and her post apocalypse contacts and also impeccable eyeliner 💅

Belphie being mean and pinching readers nose while she's sucking him off and not letting off until he finishes🥺?

-From: Goodgirly🔒

18+ nsfw, minors do not interact // dubcon, mean belphie, degrading bj, tears

"Mm...you can do better than that."

Belphie disappointedly looked down at you as he slid his cock out of your mouth and slapped it against your cheek a few times while you coughed and gasped for air.

He sighed. "Let's try again before I get soft."

Before you could take another deep breath, his hand found itself on the back of your head, while the other guided his thick cock between your swollen wet lips once more. He let out a small content hum as you gagged, your warm throat squeezing around him.

He peered down and grinned when he saw the tears in your eyes and the way you struggled to breathe. He could feel his cock getting harder. Now they're getting somewhere.

Belphie kept his hold on your head and with his other hand he pinched your nose, cutting off the only air supply you had left. You dug your nails into his thighs and struggled as your loud wet choking and gagging filled the room. Belphie let out a low groan as he fucked your mouth.

"Fuck! You look and sound so much fucking better like this."

The fat tip of his cock abused the poor narrow walls of your throat with each thrust. Big fat tears rolled down your cheeks as he continued pummeling into your face, balls slapping against your chin. You tried to push against his arm, his thighs, anything to at least let you breathe a little but his strength was unmatched compared to yours.

"Hah...! You can breathe when I'm done! Oh fuck, fuck, almost there—!"

With a few more harsh thrusts, his hand finally let go of your nose as he reached his peak. He moaned as he spilled his cum down your throat; while you desperately breathed in as much air as you could.

Once he was finished he slid his cock out and admired the piece of work left on the floor.

Your hair was a mess, tears still running down your cheeks, and drool covering your chin all while you coughed and gulped in globs of air.

Belphie could feel his cock stirring once more. ⬦

Prompt #183

“You’re smaller than I expected.”

“Yeah? Well, maybe you’re just abnormally tall.”

[vampire-scones]

Do you think Steve cries himself to sleep at night, not because of everything he’s seen, but because he’s finally come to terms with the fact that he loved Billy. He yearns to kiss him, to have a moment where they let out all their rage and anger in a hate fuck and then continued on to touch each other softly in the morning light. Cries about them laughing and exchanging high school stories and sharing soft kisses in the golden hour glow. But he can’t, because he watched Billy die, 10 feet away from him. And he’ll never know if that boy felt the same or if he would have decked Steve for even having such thoughts. But he still cries, because he wants to touch or be touched by Billy one last time, even if it’s just a kiss from his fist.

[whumpster-dumpster]

Just had the phrase "Lost in the sauce" pop into my head where it's a tiny whumpee dropped into a sauce pot the whumper's bringing to a boil hehe

[strangelittlestories]

The new god of tricksters approached the turnstile that led to the mortal realm.

To the side of each turnstile was a booth. And in each booth sat a psychopomp - the guides and guardians that stood between realms. 

The lines were short as it was early afternoon during an Age of Reason, where new gods were not in high demand (as opposed to an Age of Reasons, plural, when the world churned through fresh deities to excuse all kinds of bullshit).

The new god was nearly at the front of the line. Ahead of them, a new genius loci of a small scientific library approached the booth. They were interrogated by a psychopomp who was 90% alligator teeth and 10% your mother’s disappointed eyes.

After a short conversation, the science spirit was eaten for being a contradiction-in-terms.

The trickster god stepped nervously through the gore of poorly edited academic citations.

“Hi.” Said the god, plastering on a smile.

“Name and nature?” The psychopomp’s grinding tone suggested it had neither the interest nor the bodily architecture for engaging on smalltalk (and would only be let down by your efforts anyhow).

“Interesting question. For part A I’m not sure I have one yet and I’m getting the feeling I *may* want to keep it secret anyhow. As for part 2 … I think my answer to part A might give you an inkling as to my nature.”

Imagine a creature made of many tiny bone knives coated with the venom of parental mortification. Imagine it sighing. The kind of sigh to end a universe or ruin a graduation.

“I have to fill out the form.”

“Tell you what … you’ve got most of a form already filled out from the poor sod before me.” The new god tried out a grin for the first time. “I’ll just give it a quick edit, bring it up to your standards, then presto theologio, god’s a good’un.”

“...it’s against the usual policy. But I do kind of want to see how this plays out.”

“Your confidence is appreciated.” The god fine-tuned their grin, turning up the sharpness and turning down the symmetry.

“Oh no.” Too many teeth smiled back at the god. “I just want to see how badly you’ll fuck it.”

The god decided not to press their luck and busied themselves with the form. They even kept their doodling in the margins minimal. Towards the end, they looked up at the psychopomp and asked:

“I think there’s a typo here. It’s asking me if I want to take out enhanced faith-based ‘lie-ability’ protection on behalf of my prospective followers?” The god indicated a part of the form with a finger that was entirely new to pointing and doing a bang-up job. “Surely that should be ‘liability’? As in, do I want *them* to have legal protection in case they get caught doing trickery? Or do I want to protect *myself* from being held accountable for their actions?”

“No typo. Special offer for tricksters. ‘Lie-ability’ - as in, for your followers’ faith to let them prevaricate more proficiently. For the strength of their belief to drip like ink from their tongues and rewrite the world into a more *pleasant* story.”

“Well, at five Revelations and ninety-nine Inspirations per century, it certainly seems like a steal. And I think I might be into stealing… Sign me up.”

“As we say in the business:” The psychopomp winked disconcertingly. “If your followers are *able to lie*, you’ll never be *liable*.”

Later, the god of tricksters might regret not asking why the previous applicant’s form had had a special section for trickster gods.

Or they might not. Some stories were more fun if you didn’t get bogged down in the details, after all.

Writing Modern Steve Roger's Health Issues: A compendium

AKA How do Steve Rogers' MCU canon illnesses hold up in a modern setting?  

I am writing something that is SO NICHE and so NERDY I feel absolutely, positively deviant about it. Who knew you could have this much fun while eating a burrito and sitting in the sun on your back porch? 

OKAY! This one goes out to all of you writing modern AU's with a modern Steve Rogers. (There are literally dozens of us!). Let's go.

So, I find it somewhat problematic when people write disabled or otherwise medically complicated characters and are wishy-washy about the diagnosis they have. In real life, everyone I know with ongoing medical issues is a fucking expert on their exact shit. A great tumblr reference for disabled characters is Cripple Characters, but I also use reddit threads to read about people’s day to day experiences with different issues in their own words. If nothing else, just decide what your character has and take ten minutes and read through a basic website article about it. 

So let's walk through what modern Steve's medical history and diagnoses might be. If you feel like I missed any details or got things wrong, happy to have comments to that end.

We'll start with the list of “ailments,” going with the MCU canon and combining the images from the museum exhibit and screen shots of Steve’s enlistment forms:

Asthma

Scoliosis

Fallen arches

Partial deafness

Scarlet Fever, Rheumatic Fever

Heart arrhythmia

High blood pressure

Palpitation or pounding in heart

Easy fatigability

Stomach ulcers

Pernicious anemia

Nervous trouble of any sort

Sinusitis

Chronic or frequent colds

Caveat: I am not a doctor, but I am a person who enjoys reading medical journal articles about illnesses I do and don’t have. The human body is a fascinating and terrible place to live. Talk to me about your medical complications - I will always find them interesting. I love small talk about Crohn’s disease and/or extremely graphic details about the time you had surgery because one of your wrist bones was the wrong length. 

Sucks To Your Assmar: Asthma! How has asthma changed? 

Kids who have their asthma well managed at a young age are going to have less scarring and lung damage (this is called airway remodeling). Thus a modern kid will likely have less severe asthma than a kid born in Steve’s time. Further, allergy medicines got way better from the 1990s, so kids with allergy induced asthma would have had fewer attacks. Fewer attacks as kids = less severe asthma as they age. 

I would also note that asthma is highly connected to environmental issues. If Steve grew up in a house with cigarette smoke, cockroaches, rats, or mold present, as is fairly easy to imagine, especially without dehumidifiers in a swampy Brooklyn summer, those are environmental factors that would have made his asthma much worse. 

They are also all factors that kids today certainly face, depending on how you write your modern Steve’s childhood. While people today certainly can have very severe asthma, it’s also entirely possible that modern Steve’s relationship to his asthma is pretty chill and easy to manage. (My partner has relatively severe asthma with a lot of environmental triggers; modern allergy medicine was a big game changer.)

Let’s talk about scoliosis ~~

There are a lot of variations to how scoliosis impacts people. I have very minor scoliosis and it's barely a thing in my life. I’m not trying to speak for everyone, but for what it’s worth, there are professional athletes with spinal fusion. I used Kyra Condie as my justification for writing climbing coach post-spinal fusion small Steve Rogers in one fic. My younger brother and best friend in high school both had spinal fusions. 

In reality the athletic and physical abilities of people with spinal fusion vary pretty much exactly as much as people without spinal fusion, so you have a lot of leeway for how you decide to write a character with scoliosis. I recommend reddit threads to read about people talking about how their bodies felt before and after spinal fusion, or why they decided not to have the surgery, if you want to get a sense of how it might affect your character’s day to day life.

Wait, so how tall is modern small Steve Rogers? 

You can see in this article that gains in height post scoliosis corrective surgery/spinal fusion varies, but the mean was 27 mm (1 inch) and the maximum was 66 mm (2.5 inches). 

The more severe the curve in the spine, the more height gained with surgery. 

We know Steve had scoliosis, we don’t know how severe it was (do we?). But if he was 5’4” without spinal fusion, and with all of his childhood fevers, and possible poor nutrition due to the Great Depression and untreated stomach ulcers, then it’s very reasonable that a modern Steve raised with proper nutrition and his gastrointestinal issues (see below!) properly treated and a spinal fusion could be easily 1-10 inches taller. 

I think it’s great if you want to write modern Small Steve as 5’4” - but I tend to write him as 5’7” or so. 

I think it is entirely likely that a modern Steve Rogers could end up being 6 feet tall given modern medical intervention and a healthy digestive system and adequate nutrition. As an example of how people with more or less the same genetics having different heights due to environmental factors, I know of one family of four brothers that immigrated from Italy in the 40s. Their height was 100% correlated to their age when they moved to the US/started having access to food: the oldest brother was around 5’4” and the youngest around 6 feet. The oldest was also a chain smoker and worked full time from around age 8, so you know, he was a fucking badass 5'4" Italian guy, if that's not clear.

What about fallen arches? 

Fun story, but I have fallen arches/flat feet and had a lot of foot pain as a kid, but I thought it was normal. I wear custom orthotics and/or birkenstocks and do exercises to strengthen my feet muscles and it's fine now as long as I remember to do the things I just mentioned. My dad had to have multiple surgeries on his feet, so I think it helped that they caught it earlier in me. 

Should I write modern non-serum Steve as deaf? 

Maybe! I think it’s lovely when people write characters with hearing issues. There are great blogs that cover ways to do that well (a good link, another one, and another one and I think this one on hearing aids is particularly good if you are trying to bring in subtle day to day routine differences a character that wears hearing aids may have. Another great option is, again, reddit, especially for questions around how sexual intimacy might vary in small ways that can be nice to bring in. (I am working on a fic with a seeing character whose ex is blind and also read a lot of couples first hand experience with sexual intimacy around that dynamic on reddit). 

But how likely is it that modern Steve would be deaf? 

I think that it’s reasonably likely that Steve’s hearing issues were a result of Scarlet Fever, which is a bacterial infection that can result in rheumatic fever, an inflammatory condition that develops in more severe cases of scarlet fever. 

Scarlet fever caused deafness - in fact, both Helen Keller and Thomas Edison had hearing loss due to scarlet fever infections. Further, sustained fevers of over 104 degrees can also cause hearing loss, so there is a reasonable chance that some other fever caused Steve’s hearing issues. 

Today, the kind of hearing loss caused by fevers and infections can usually be surgically repaired or never occur because we have better antibiotics and better medicines to treat fevers. However, I have a friend who has partial hearing loss and lots of other life long nervous system and fatigue issues due to complications from childhood chicken pox in the 80s (this vaccine came around in 1995).

I don’t know if it’s canon or fanfiction, but I often see Steve as having one bad ear. For what it’s worth, hearing loss in one ear is much less common than hearing loss in both ears. 

However, potential causes of hearing loss in one ear are infections that result in a high fever and some kind of head trauma, both of which are easy to imagine would have affected a Steve born in 1918, and while possible in a modern Steve, also easier to avoid. 

Heart Stuff: Heart arrhythmia, High blood pressure, Palpitation of pounding in heart, Easy fatigability

The aforementioned fevers that can cause hearing loss can also cause heart issues. I think it’s reasonably likely that Steve’s heart issues were from his fevers as a young kid, but I often write him with a congenital heart defect, because why not? 

These days, most of the time, such issues are detected at or before birth and fixed when the person is a baby, but there are plenty of heart issues that can require multiple heart surgeries at various points. Regardless, a modern Steve would most likely either have had access to corrective surgery or medication to manage these heart conditions. Which is not to say that he wouldn’t suffer mental and physical trauma from this medical complication. 

There are plenty of professional athletes you can find who have all of the above heart issues. And plenty of people with heart issues who have no interest in being professional athletes, so like, follow your bliss. 

Digestive System Stuff: Easy fatigability, Stomach ulcers, Pernicious anemia

I have easy fatigability under heart stuff too, because lots of shit can make you tired. 

My personal head canon is that Steve Rogers has celiac disease and/or lactose intolerance, it would cause all of the above. Both can also lead to poor growth - in fact falling off growth charts is one of the most common symptoms of celiac disease in children. 

While people have been aware of celiac disease since there were people, gluten wasn’t identified as the clear cause till the 50s. 

I typically write modern Steve with some kind of food allergy, and I think that addresses quite a few of his canon medical complications. 

Because so many causes of this category of symptoms are relatively easily solved with modern medical intervention/avoiding the problem, I would point folks towards Crohn’s disease if you are looking to write a modern character with medical issue that is more likely to be an ongoing source of similar medical complications today.

(Also, kids with Crohn’s are likely to have reduced height. I have a friend who has Crohn's whose 3 siblings are well over 6 feet and he is around 5'8" (so 4-6 inches aka 11+ cm shorter due to his severe childhood illness).)

Nervous trouble of any sort

Kids with medical complications and food allergies are much more likely to have anxiety. I’m so proud of all the kids making it through the day with anxiety. Luff you anxiety kids, I see you working twice as hard to be present as the non-anxious kids. Tough as hell. Give yourself a high five. I’m so damn proud of you.

Sinusitis and Frequent colds

I mean, god bless modern decongestants and allergy meds. Celiac disease and lactose intolerance can both cause sinus issues, so here is another one of Steve's ailments that can be "cured" through that diagnosis.

Other stuff

When you look at the above, you can see a lot of scenarios where modern era Steve, like many children/adults today, had multiple surgeries and serious and scary health complications as a child, but as an adult would appear as a relatively healthy able bodied person, with the possibility of even becoming a top athlete if he was so inclined.  It’s also likely that some issues like chronic fatigue etc, might linger into adulthood as relatively invisible illnesses that nonetheless affect his everyday. 

In some ways his character arc given the advances of modern medicine could mimic his arc due to the serum. 

Being medically complicated as a kid sucks. Even if you have surgeries to treat and/or learn how to live with things like Crohn’s and celiac and reduce flare ups, lingering mental health trauma can have an impact. 

Lastly and most importantly, I have a personal headcanon that young Steve Rogers of any era spent a lot of time sick in bed and staring into a mirror learning how to raise one eyebrow and perform other eyebrow gymnastics so he could more effectively sass his nurses. 

IN CONCLUSION:

I think it's actually reasonable for an author to say, "My modern Steve never had any fevers, and got his severe lactose intolerance diagnosed as a baby, and had good nutrition, had medications/clean environment that prevented his asthma."

So this Steve is 6 feet tall and healthy as long as he doesn't eat dairy and takes his daily zyrtec (cetirizine - it's an allergy med). The only medical issue he has from canon left is scoliosis, flat feet, and an astigmatism.

You can also choose to write a Steve with more complex medical issues, and there are lots of things that can be good and interesting and value about that. I think the main thing is to pick a diagnosis and write it realistically, hopefully this helps some with that!
