You're curious at least, judging by this post. Do you fantasize about women sexually? Or do you also have a potential romantic interest in them? Just in case you're unaware of this: it is possible to be bisexual and heteroromantic. Or any other combination where sexual interest and romantic interest don't line up.

Once you start falling for a woman, I'm guessing there'd be no plausible deniability. Unless and until that happens, bicurious probably best describes your romantic interest.

Sexually speaking, something that turns you on has a non-0 chance of not being equally appealing to you once you act out the scene in real life. There's only one way to find that out for sure. Again I'd probably call it curiosity until you've crossed that bridge.

Anyways, do labels really matter? Are they helpful? I'd just go with the flow if I were you. And I'd encourage you to try out whatever interests you. You only live once and I can't imagine you upsetting any gay/bi women just by being yourself.
