I'm still trying to figure out how "non-homophobic" entered the conversation. Non-homophobic would mean, to me, that you have no problems with gay people. If you want to say that you are curious or open, you could use the popular "trisexual"--you'll try anything once. That's always said to me, I'm not going to hold onto a particular label at all but if I'm in the mood and the circumstances are right, I'll enjoy myself with who ever tickles my fancy.
