Individual confusions should not come into arriving at a generalisation. One MAY choose to suppress one's attraction for the opposite sex to ape the gay norms, but one CANNOT deny the fact that opposite sex was capable enough of inciting him/her at some point of time, if it had been the case. Being a gay myself, I cant remember any bi lanes I had to scramble through. And I wont deny the existence of them either, unlike the author.
