Would it be possible for you to do the second half of that Saïx nsfw alphabet? >/////< if not no problem what so ever and you can totally ignore and trash this!

It’s certainly possible, and I’m glad you care enough about my headcanons to have asked for more! ^-^

• N = NO (Something they wouldn’t do, turn offs)
  He’s really put off by excessive whining and begging. He has no problem with knowing that you need him, but there’s a line and once you’ve crossed it, he’s really just… uncomfortable. 
• O = Oral (Preference in giving or receiving, skill, etc)
  He prefers to receive for a lot of reasons, but isn’t entirely against giving, mostly as an act of foreplay. He’s pretty good at it, would be better with practice. 
• P = Pace (Are they fast and rough? Slow and sensual? etc.)
  Slow, but rough. 
• Q = Quickie (Their opinions on quickies rather than proper
  sex, how often, etc.)
  Quickies are a no for him; he much prefers to take his time. If it’s going to be done at all, it needs to be done properly and thoroughly.
• R = Risk (Are they game to experiment, do they take risks,
  etc.)
  He’s not really very adventurous in that regard, and the most risk he takes is the possibility of getting caught.
• S = Stamina (How many rounds can they go for, how long do
  they last…)
  2 rounds, 15-30 minutes each. 
• T = Toy (Do they own toys? Do they use them? On a partner or
  themselves?)
  No. 
• U = Unfair (how much they like to tease)
  A lot. An unfair amount, considering. 
• V = Volume (How loud they are, what sounds they make)
  Relatively quiet, mostly grunts.
  His hands are what really express his enjoyment, the way they grab, hold, and caress.
• W = Wild Card (Get a random headcanon for the character of
  your choice)
  He is concerned with his partner’s pleasure, and checks in with them frequently, he just also sees sex as kind of a physical necessity more than a whole-self need. It’s a thing to do, and while he likes doing it with his partner solely and specifically, it’s not about their relationship, really.
  He expresses his care for them in other ways. (He’s a “take a jacket, it’s raining” means “I love you” kind of guy)
• X = X-Ray (Let’s see what’s going on in those pants, picture
  or words)
  Solidly average length and girth, and/but more than sufficient to do a job well, no curvature, just… well, it’s almost beautiful, actually. 
• Y = Yearning (How high is their sex drive?)
  Depends on his health. When he feels good, it’s higher, when  he doesn’t, it’s lower. 
• Z = ZZZ (… how quickly they fall asleep afterwards)
  He doesn’t. Or rather, his partner is already solidly asleep by the time he’s even drowsy.
