Virginity is a complicated concept. Essentially the definition for virginity is different for every single person because virginity pertains to the individual. It's difficult for everyone to agree on one meaning because it's such a subjective thing, and so many things factor into it. Personally I feel society would do a lot better if we put a lot less emphasis on the importance of virginity, but that's another discussion entirely, and one I won't get into here.

I can only give you my personal definition of virginity. In the past two years I have discovered I am pansexual, but up until then from the time I was fifteen I knew I was bisexual. For me, I considered virginity to be virginity: my first sexual experience. It happened to be with a male, so we had heterosexual intercourse, but if I had interacted with a female first in that way I would have still considered myself to have lost my virginity. What's sex (and, ergo, the loss of virginity) to me? Any form of consensual oral, vaginal, or anal intercourse, including the use of sex toys, with one exception: I consider manual stimulation between women to count as a sexual experience, but not manual stimulation between a male and a female. Again, this is MY definition of intercourse/loss of virginity. Everyone here may give you a different answer. In the end, you have to decide what is right for yourself.
