First of all, we all know that he would be into some bdsm shit. He just gives that vibe. No doubt in my mind he would enjoy having sex in the air. He's used to being in the air for his job, so why not his sex time?
I also be that he would enjoy shibari. He gives the vibes of being a Dom even tho he's small. He likes to take charge and show you whose boss.
This next one is a bit crazy but I could see him liking knife play. He was good with a knife as a kid and he uses swords now, why wouldn't he use that skill in his sex life? There is no doubt in my mind that he degrades people. He does it 24-7 to everyone but he takes the degrading a little bit differently, he does it in a more loving way. In his way he shows you that he loves you and that your still his top priority.
AFTER CARE
He gives you a nice bath making sure that your relaxed and clean. Once he thinks your clean enough he drys you off and makes sure you have comfortable but sexy Pj's on. He changes all the bedding before letting you get in bed. Once the sheets and bedding is clean and made he carries you back to bed and lays you down and tucks you in. He cleans himself as fast as he can so he can be little spoon before you fall asleep. Tho he is dominant he likes being held and loved. You play with his hair and eventually fall alseep for the next day to come.
