Well, being a very queer system, I think I can give a weird answer to that question... I'm a pansexual transfem jolteon that enjoys being on either end of extreme sub or dom, but in here there's also a (not really furry) genderqueer lesbian, a gay male bearded vulture, and an asexual femboy kitty, but I don't know more than that about their orientations.
If you're going to ask how all that works, I'll keep it simple: it doesn't. xD
