If she passes the 'well I'm turned on' test and I really like them as a person dating is certainly possible in theory (not sure I'd care if its gay or not - its not a problem for me to care about). As for the sex, I cannot express how much of a turn off 'sword fighting' (or better chosen words) would be for me. I just don't think it's something I could mentally do (I guess that makes me straight), so perhaps I could admire them. But I just don't think sex would be something I could do.
