Y'all already know.
AGED UPA= Aftercare (what they're like after sex)
Hun he treats you like royalty. He doesn't seem like he would be great at it, but you're his and he wants to take care of you. You're his most prized possession and he treats you like that.B = Body part (their favorite body part of theirs and also their partner's)
Hands. He knows that both of you know how much it drives you guys crazy. They're super useful when you guys have sex.C = Cum (anything to do with cum, basically)
High key has a breeding kink.D = Dirty secret (pretty self explanatory, a dirty secret of theirs)
It turns him on when you slap his ass even as a joke. It's really weird and funny.E = Experience (how experienced are they? do they know what they're doing?)
He's not experienced but he learned very quickly. And honestly you would not have expected he was a virgin when you first started dating. He just did it so well.F = Favorite position (this goes without saying)
Doggy. Yeah.G = Goofy (are they more serious in the moment? are they humorous? etc.)
He's a combination of serious and funny. He's right in the middle.H = Hair (how well groomed are they? does the carpet match the drapes? etc.)
Not comfortable :)I = Intimacy (how are they during the moment? the romantic aspect)
Like I said during G, he's right in the middle of being serious and being funny.J = Jack off (masturbation headcanon)
Sometimes prefers masturbation to actually having sex with you.K = Kink (one or more of their kinks)
Orgasm Denial (G)
Praise (G + R)
Degrading (G + R)
Roleplay (G + R)L = Location (favorite places to do the do)
Bathroom. Inside the bathtub, against a wall. Doesn't matter.M = Motivation (what turns them on, gets them going)
If you bend over. There are other things but that shit is a turn on for him.N = No (something they wouldn't do, turn offs)
He's not really into toys or bringing kinky shit into sex. Also like he won't even watch something if it involves non consensual sex.O = Oral (preference in giving or receiving, skill, etc.)
He loves giving. He loves driving you insane with his mouth. He's great at it, but let's just say T E E T H.P = Pace (are they fast and rough? slow and sensual? etc.)
All depends on what you want. He can definitely do both, and is almost always willing to do whatever.Q = Quickie (their opinions on quickies, how often, etc.)
He's pretty into them if they're needed, but other than that he prefers not to.R = Risk (are they game to experiment? do they take risks? etc.)
He's not really into that shit but he will if you're into it.S = Stamina (how many rounds can they go for? how long do they last?)
He can last about two or three. They go on for about 10 minutes.T = Toys (do they own toys? do they use them? on a partner or themselves?)
Not really unless you have them and want to use them.U = Unfair (how much they like to tease)
He'll tease but he's not completely terrible and will let you have it after a while.V = Volume (how loud they are, what sounds they make, etc.)
He's pretty quiet, actually. No one's ever found you guys because you're pretty quiet.W = Wild card (a random headcanon for the character)
He has scratch marks (that left scars) on his back from you that he once said he was attacked by a wild animal until he realized that saying it came from sex was cooler.X = X-ray (let's see what's going on under those clothes)
He's above average ;)Y = Yearning (how high is their sex drive?)
It's a bit higher than the average ;)Z = Zzz (how quickly they fall asleep afterwards)
It all depends, really.
