A request I got on tumblr. Literally first headcanons with IRL humans I'm doing so I'm still feeling kind of awkward about it... please don't eat me. I been good.

Outside, he's a perfect gentleman, only holding hands in public, giving you short pecks on occasion and not doing anything that could be deemed inappropriate. He doesn't have a huge need for physical contact in general, but he actually enjoys it way more than it seems until it happens. He will initiate contact at a reasonable volume, but will never tell you no if you initiate it too. Because in truth, his heart always beats faster at the thought of some cuddly time.
Although he's not into too much of PDA in this matter, he'll never refuse it if he feels like you may need it. He doesn't mind either holding hands or not holding hands, and if you lean your head on his shoulder in a bus it'll be just fine with him either.
It's never too serious with him. He's one shit of a tickler though, and if you feel like he's being too calm at the moment, just don't trust him. He'll start to tickle you when you're already in his grasp, unable to flee. But after a while, if he gets tired of it, he'll just wrap arms around you and rest his head on your stomach, letting the both of you catch a breath and relax. In no time you'll be lying there, limbs tangled together, just enjoying each other's presence and having some small talk, bursting into giggles every few seconds.
He likes to praise you at times like this. Somehow, he can't stand just lying in one place, he'll want to place soft kisses all over your skin of arms and stomach. He'll be more than happy if you want to do that too, he'll hold you even closer, filled with happiness to the brim.

At first, it may seem as though he doesn't feel good with physical contact. In truth, before you get to know him better, it'll seem as though he doesn't need or even want it at all. Even once you're in a relationship, the physical contact will be kept at minimum. If you're the one to initiate it he'll probably be pretty uncomfortable at the very beginning, unsure of how to proceed it. And if you're too stubborn, it may cause him to freak out. But as the time passes and the two of you get closer, he'll start to open up and you'll surely notice that he's more and more just okay with it. And at some point, he'll start to initiate it too. He just needs time to learn to enjoy it – he will, though.
At first, anything that would restrain his movements or cause too much of direct skin contact would be too much for him. He wouldn't mind you wrapping yourself around his arm and leaning your head onto his shoulder, and that would be a good beginning. Holding hands would also be quite nice, but he would rather have either yours or his own hand wrapped in a sleeve, so that the skin doesn't touch directly. With time, he'd enjoy it if you randomly came to him to hug him just for the pure fact of it, as long as he's not too busy at the moment and you don't stay like this for too long.
As the time passes, he'll figure out that he likes to initiate it, too. He'll randomly catch you in his hoodie and refuse to let u got for some time. It'll seem as though he just wants to tease you, but in truth, he wants to feel you close to himself just for a bit more time, bury face in your hair and just let himself drown in the comfort you provide him.
The best time to get him into a cuddling session is when he's naturally too lazy to refuse. I recommend you lay next to him on a bed and just make your way to his heart arms. Don't lay on top of him he's fragile, so handle with care but if you're already in his arms, it may last hours of no movement at all. Just don't annoy him with too much movement, he will throw you off if you do.

He may enjoy the physical contact, but whether or not he'll initiate it, will depend on whether or not he feels like you're comfortable with it. He's definitely the one to put you above himself and if he senses that cuddles are not your thing, he will never pry. Oh, but since you're reading this, you're probably not the one to dislike cuddles. Hobi is good at spotting your boundaries and whether he should hug you, hold your hand or just keep his distance.
