There's a story here, Watson.

Willingness to experiment with other gender: Fair enough, but not a preference.

In Character Opinions of sex:

1. When it comes to full penetration, it is awkward for him even if enjoyed. His mind needs to be in a sedated state for it to not make him feel something residue-like afterward. Hence, his BDSM practices (among many other reasons).
2. When it comes to kink, he is incredibly open about it. Careful, however. Knowledgeable in the practice to not just dive on in with anyone.
3. When it comes to 'making love' it is absolutely horrifying and you can bet 100% that if he really likes you in even a remotely romantic way he will be very unlikely to have sex with you as it scares the shit out of him.
