A = Aftercare (what they're like after sex) He doesn't give a fuck about you afterwards. Clean yourself up.
B = Body part (their favorite body part of theirs and also their partner's) He actually doesn't mind his scars all that much. As long as they keep people from prying into what he's trying to do. Sometimes they remind him of his past, which serves as a reminder why he's a villain, doing what he's doing. On you, he likes playing with your hair.
C = Cum (anything to do with cum, basically) It might be slightly hotter than usual because of his quirk. He loves seeing it on you or in you. He wouldn't be too pleased if you swallowed without him getting to see it.
D = Dirty secret (pretty self explanatory, a dirty secret of theirs) He won't hesitate in a moment during sex to burn you if you defy him, but he might feel guilty later seeing the scar he left. He also thinks Hawks is kind of hot, but he won't admit it.
E = Experience (how experienced are they? do they know what they're doing?) Despite his appearance, with all the money he 'borrowed' from his dad, he had plenty of chances to get with people, and has a pretty good amount of experience.
F = Favorite position (this goes without saying) He loves any way he can see his dick going into you. He's always a top dom, but if you somehow beat him for dominance he'll let you have it once, and secretly like it, but he'll put you back in your place next time.
G = Goofy (are they more serious in the moment? are they humorous? etc.) He teases you all the time, but other than that, he'll never make a joke or anything.
H = Hair (how well groomed are they? does the carpet match the drapes? etc.) He probably keeps it hairless, not wanting to ruin his black-hair's 'natural' edginess.
I = Intimacy (how are they during the moment? the romantic aspect) He isn't really sure how to be very romantic, and he prefers just having sex. What's the point of a relationship otherwise, that's what he thinks. He got you flowers like once, and that's about it.
J = Jack off (masturbation headcanon) He prefers you, but if he's on a long mission he might do it a couple times. As long as you keep him satisfied, he never does it.
K = Kink (one or more of their kinks) Cumplay, Sadist, Gunplay, pretty much anything that makes you feel like you're in danger, even if you really aren't. That includes choking and breathplay.
L = Location (favorite places to do the do) Probably on a bed, he doesn't really like doing it in public. He might do it in a restroom or somewhere slightly more public if he's desperate, though.
M = Motivation (what turns them on, gets them going) If someone else is hitting on you, and you seem to be enjoying it, he'll teach you a lesson on who you belong to. He gets jealous easily, afraid that you'll leave him.
N = No (something they wouldn't do, turn offs) I have a hard time thinking that he has any. He both loves and hates being called daddy, because for one, it shows him you know who's dominant, but at the same time he thinks it's really weird, especially how he hates his dad. He doesn't like it when you think you can be dom.
O = Oral (preference in giving or receiving, skill, etc.) He prefers receiving, but he'll give it too if you want him to. Just be prepared to beg for it, and you'll get it.
P = Pace (are they fast and rough? slow and sensual? etc.) He starts out pounding you, but he becomes slow at the end, preferring the sheath himself inside you and feel your walls constrict around him.
Q = Quickie (their opinions on quickies, how often, etc.) Since he's a villain, he hardly ever has time for actual sex, even though he prefers it. Mostly all you two will do is quickies, but he doesn't really enjoy it very much. When he finally finds himself with free time, you better be in the bedroom ready for him, or he'll drag you in there and throw you on the bed.
R = Risk (are they game to experiment? Do they take risks? etc.) He doesn't mind risk, but he just doesn't like doing it in public. Like I said before, he would do it in the bathroom without a second thought.
S = Stamina (how many rounds can they go for? how long do they last?) It really depends on the situation, and how aroused he is. If he has the free time, he could stay up all night with you, edging himself until he finally cums in the morning.
T = Toys (do they own toys? do they use them? on a partner or themselves?) He definitely owns a lot of toys. He loves trying out new sex toys on you, seeing the new ways you come apart for him. He usually wouldn't use them on himself, preferring to use you instead.
U = Unfair (how much they like to tease) He is the biggest tease. If you have nipple piercings, he will twist and touch them all the time.
V = Volume (how loud they are, what sounds they make, etc.) He gently moans in that deep voice of his right before he cums. Other than that, it's mostly incoherent muttering about how good you feel against him. He might start gasping if he is edged for too long, but he won't admit defeat until you've came first.
W = Wild card (a random headcanon for the character) Being with him he would like to stay mysterious as possible, all part of his angsty-twenty-year-old vibe, but if you stay with him long enough, he'll tell you his secrets because he trusts you.
X = X-ray (let's see what's going on under those clothes) He has multiple piercings on his dick, no doubt. He loves seeing them go in you and stimulating you. It's one of the few parts of him that isn't totally burned.
Y = Yearning (how high is their sex drive?) Once a day. That's what he wants. If it's only a quickie, he could do a couple.
Z = Zzz (how quickly they fall asleep afterwards) He won't let sex effect his sleep schedule, so if he was tired before, he might sleep, but otherwise he will just tuck you in and let you sleep.
