Just my opinion. It's kinda like that for me, only the other way around. I'm almost homosexual but there are a couple of guys that I'm attracted to as well. I just say I'm bi with a preference for girls.

I was in the same type situation, I rate myself a 1 on the Kinsey scale, but I just call myself Bi now {^^^ as anaswill said, except mine is with a preference for guys}.

Bi doesn't have to mean you're equally attracted to both genders, it can be any percentage, ie. 95% attracted to the opposite gender and 5% attracted to the same gender.
