D, F, J, X, Y for Sidon. – Flurry.

D = Dirty Secret (Pretty self explanatory, a dirty secret of theirs)
He’s fascinated by humans and how different they are from him, to the point that actual scientific comparison kind of turns him on just because he’s so busy thinking about his partner
F = Favourite Position (This goes without saying. Will probably include a visual)
See, sharkskin is super rough, so there are very few “normal” positions he and his partner can comfortably get into. He’d like to have them on his lap. but straddling him requires their inner thighs to drape over the outside of his…. ouch. He tends to just open his legs and let his partner get comfortable. It’s no fun if they’re in pain, after all (but when they aren’t in pain? It’s very fun)
J = Jack Off (Masturbation headcanon)
The Prince cannot do such a thing (… unless he’s by himself in his resting pool, staring up at the stars and thinking about his partner)
X = X-Ray (Let’s see what’s going on in those pants, picture or words)
I AM A BIOLOGY MINOR HE HAS CLASPERS
Y = Yearning (How high is their sex drive?)
Not crazy high, but he has his moments where he drags his partner either into his sleeping pool or behind a wall and is like “please, pearl in my ocean and moon in my sky, I need your body against mine.” also ruts are sort of a thing, and pheromones to some degree (he’s very attentive to any female’s partner’s hormonal fluctuation because he can smell the changes on her)
