thinking about f/os who are like 20x your size treating you so gently. with minimal effort they could squash you flat or grind you into dust. but they would absolutely never do a thing to hurt you. maybe it took them some time to train and learn to treat you gently, as they'd never had any kind of relationship or contact with someone so much smaller than them. they see you as so precious and want to treat you accordingly, and you want to learn how to give them affection.
you stop seeing them as intimidating or scary... instead, you begin to see them as your protector. they could defend you from any threat this planet (or any others that you and your f/o may live in) might throw your way. your f/o is very proud of this, and wouldn't hesitate to keep you safe with their superior abilities. maybe they were once the threat you faced... but not anymore. it all changes when they fall in love with you, and now they couldn't imagine threatening or hurting you.
now, your normal includes sitting securely in their huge hand that cradles you. kissing anywhere you can get to on their face that's as tall as your entire body (if not taller!). sitting on their shoulder, solidifying your place as their closest companion. their humongous hand reaches to touch your face, and only their fingertip can touch you. but that smallest touch is full of overwhelming love that it's just enough for you
