B, M
B = Body part (their favorite body part of theirs and also their partner’s)
&&. i reckon his favorite body part(s) of himself would be the same ones he'd admire in someone else. they would probably be his hands and his eyes. despite the sad bloodshed, his hands are, indeed, a useful tool. every callus and every scar reminds him of his past — the good parts, at least. it's a nice reminder of what he used to be in his teenage years. and hey, you can do a lot of things with your hands.
he also likes his eyes because they're usually what he gets the most compliments on ... lol. and they're the first thing he notices when looking at someone, so i guess their partner's eyes would be his favorite. much like hands, eyes are a tool and a mirror; they're a powerful reflection of your soul, not to mention they can be insanely beautiful. ( yes, yes … psa: if it's a woman, it'd probably also be her breasts. sorry not sorry. as for men, as long as they've got a pair of striking eyes and beautiful hands, he's good. )
however, a pretty smile can tug at his heartstrings. does it count as a body part, though?
M = Motivation (what turns them on, gets them going)
&&. i've touched on this subject before, so yes, that. but then again, it really depends on the context and the partner. tom is someone who can adapt to situations or goes along with things as they happen, if you get what i mean.
