Could you help me figure out if I could be bisexual?

I have be turned on before by passable transvestites and picture of nude men. That was years ago. I have never really acted on those felling. I like women a lot. Lately I have been looking at videos of bisexual men and gay men (not as much as bisexual men) and for picture and videos of passable transvestites. I got turned on writing this.
