I identify as lesbian even though I have been sexual with about an equal number of men and women. I use the concept of love as I see sex as a biological function. I can/could have sex with a guy because it would feel good and he was attractive enough for me (physically or mentally). There was little to no emotional connect or emotional drive to build a relationship with a guy. I seek out women and I do find being sexual with women much more pleasurable.

Like Ember said - sexuality is so much more complex than mainstream America would like us to believe. Only you can figure out what you feel and that feeling might change over time. For me.. it's been many years now since I've been sexual with a guy and not so sure I'm interested in going there again.
