I think you're deluding yourself by saying that the majority of women are into bi guys. I'm sure there are plenty of them out there, but the majority? I highly doubt it.
your not in any position to have any knowledge on the subject.
for one, women are dispicable creatures who tell their man what he wants to hear. being a straight, white, (insert other characteristics here) man.. the women in yoru life have probably told you that you , and all of your characteristics, were their "type", and down played their attraction to all other types of men.
for two, women themselves dont even know what they want untill they come across it. one day she might tell you she isnt into a certain type, probably because of limited experience with that type, but the next day she comes across a guy of that type who is attractive and now all the suddent he is her new type.
