i think in order for us to help you decide if you, in fact, are bisexual, we'll have to define bisexuality.
i would say that bisexuality is repeatedly having sex with men and women and not having a stronger preference for either, but having a strong preference for both.
i would also think that being bisexual would mean that you would have to be AS comfortable having sexual involvement with either sex.
sooooooo...if we used that as a definition, i'd say you're not bisexual at all because you haven't been down there munchin' out! you're just a horny girl and anything sexual is making you horny. if you get to the point that you're actively pursuing members of both sexes for actual sex THEN i'd say you were bisexual.
hope that helps. if you go by another definition, then the results may differ as well.
