Well, I've experimented a bit with women, one bi-curious and one full fledged bi.
One of them wore T-shirts that said "I love strippers"
the other is a friend of my boyfriend's. On the first day her and I met, she approached us, and said "I think I want you guys."
Other than that, I have no idea. If I knew, I'd have eaten a lot more lady by now.
Good luck!
