I'm glad some people contributed to answer my question. ^^
I still find it odd, though... In this case would your sexuality still be a choice (like a man, even as a woman, still liking men)? Or is it just a matter of the gender you are attracted to? My own question confuses me, admittedly. If I were a guy, I might be... bi... but lean more towards males. I don't know why, isn't it odd? That's kind of how I am now, only backwards (female, leaning toward females).
