Bi doesn't have to be 50/50.

Ah, bimpostor syndrome. I can relate, at times.

It's almost as if gender is fluid, sometimes preference.

Despite me having the very analogical experience (but as a man) I'm gonna say - who really cares? It's like, uh... Do you still like pizza if you haven't felt like having it in months? Maybe you don't but you will go back to liking it in the future? Labels are weird... I genuinely want to consider myself queer cuz I vibe better with them queers, but them gay folks I know still gonna spend time with me whether I suck cock or not, dunno if you have it the same or completely different

Forget the label. Don't even worry about what you are or might be. Just don't 'push through' things you're uncomfortable with. If someone, pretty woman or dashing dude, asks you out, just ask yourself what you want to do right then and there. If you're comfortable and want to see them again, do it, and if you aren't comfortable and don't want to see them again, don't do it.
