snooting: ohoho. bondage: doesn't care for it, binding or bound. most restraints can't actually hold him, and he'd rather hold a partner down with his own hands and body.
edging: never had the chance to play this out, but I think he'd be curious, and then really into it, with a partner he trusts. though giving, it's less fun than sexual exhaustion/overstimulation.
he is ashamed of how much he gets off on knifeplay. up to and including snuff, if allowed. it's not civilized, it's evil, he should be better than his fallen brothers -- but he isn't. his one piece of moral high ground is that he is gets consent, and respect safewords. even for the snuff.
he wants to be a decent person (at least by his understanding of the concept) and a good leader, but he was designed, he's wired to be a weapon and a conqueror and a killer. it's such an integral contradiction for him, that it has to bleed over into sex.
