I believe the better question is to ask them if they would have sex with ME.
OP: Um... yes? I mean, it depends on how humanoid they looked and felt. Like, Cerea is a definite no, despite her huge boobs, because I would never want to fuck a horse. Morrigan, on the other hand? Yes, yes, a million times yes. Zombies, however, are most certainly on the "no" list, if only because I think they would A: still be cold, which sounds really unpleasant, and B: are still technically considered corpses and that would fall under necrophilia, which is a felony, my dear children.
