I have reached a point in my life, however, at which my v-card is in a confusing state. As a bisexual, I can easily imagine myself with a woman or a man, but I never know how to define "sex." With a man, it's easy: sex is simply sex, and if I have sex, I am no longer a virgin. Simple, clear cut, to the point. With a woman, it's more complicated; I've talked to experienced lesbian and bisexual women, and their answers differ. Some have told me fingering can be considered sex, others say oral, and some said that a sex toy needs to be used. I guess my confusion comes from the fact that I can (and at some point probably will) sleep with a person of each gender, but if I sleep with a woman first, how will I know when my virginity is nulled? I highly doubt there is going to be some lightening bolt of knowledge or some cosmic vision or something, and I find the hymen argument silly (I mean, come on, it can break riding a horse. Does that mean Stanley the Stud has taken my virginity?). And if oral or fingering is sex with a woman, do those actions carry over to being sex with a man if one is bisexual?
For me, at this moment, I define sex as the most intimate moment you can share with another person. I don't know what that necessarily is, but I'm willing to bet it's going to be an interesting journey finding out.
