I can't even answer that poll because nothing in the show indicates the answer. GBG is the only time Tosh shows same-sex attraction in the show though. She seems pretty open to it too. I think her sexual response to Mary is genuine. Whether she'd label herself as bi as a result is an open question. It's more fun to think of her as bi, so that's what I prefer, but I don't think there's any evidence one way or the other. Unless you take her more numerous relationships with men to mean she was basically straight. So, do you see Jack as the Manly Man saving Tosh? There doesn't seem to be any sexual subtext to their relationship in GBG.
