Now we could confuse the situation by throwing in the fact one of them could be Bi-curious, he agrees to try male company but only in the presence of a lady, he then decides no this is not for me, ok he's had sex with a guy, decided it's not for him, would you still consider that guy Bi-sexual or a bloody ejit for giving into his curiousity in the first place??
