Am I a lesbian? Not so sure anymore..?

k, so i like chicks for sure, but would never watch lesbian porn, but WOULD have sex with a woman. I have watched hetero and gay porn, though. But if i see a guy C**, i actually gag. literally.I could see myself being with a woman for the rest of my life, but i feel like i would only have a one night stand or short (one month) relationship with guy. I wear mens clothing, have a short haircut which is why i find this a bit confusing. I'm not sure if this is true, but i think i may be watching gay porn, be willing to have a one night stand with a man, for curiosity reasons. What do you think? i was pretty sure I was a lesbian, but now I'm not so sure.
