How to explain my sexuality

First off, I'll say that I do not necessarily know what to call myself in terms of sexuality. I'm not saying this because of confusion exactly, but I do not know how to explain my sexuality to someone. I'll say that I am a 21 year old virgin who has no interest in ever getting married or anything like that necessarily, not even sure if I would ever see myself in any kind of relationship. I definitely am attracted to women sexually and also romantically. I have gone out with a couple but it never has really gone anywhere. Never had sex or even kissed though. I know that's pretty pathetic but it is what it is. Although I am attracted to women, I also have these fantasies involving men that I do not see myself ever acting on. Part of this may be due to social reasons rather than personal ones though and although I certainly would not identify myself as gay or even bi, I don't know what I should think of myself as and what I should "call myself". I have often been very sexually frustrated but that was simply because of my falling to society's conventions that a 21 year old has to must have had sexual experiences
