it's nice to know that other people are concerned about this as well. personally i have a GF that i love more than life itself and would never cheat on her, but i do find the idea of having sex with a man appealing. most likely i would never act on this fantasy (cause i can't convince my GF to have a threesome) i still consider myself Bi or at least Bi-curious. the thing is if this fantasy is ever acted out, i may not like it and go to being straight but i think it's best to keep my mind open about it.
Same with me. I am married and love my husband, but I love to look at and fantasize about women. I have never been with another woman, but I still consider myself bisexual.
