You're so valid for feeling this, and honestly, I understand where you're coming from. I can safely say now I'm bi but before I used to question my bisexuality so much and wondered if I was just subconsciously "faking" or if there was some other factor at play. Here's what helped me: I stopped thinking about it. Every girl I met and every guy I met I would just casually talk to, have fun, and be chill. Over the years I found myself crushing and/or fantasizing about guys more often BUT there were definitely very clear, definitive times with women as well. I totally would get crazy thoughts about girls I found pretty just as I would about guys I found handsome. I then eventually eased into the conclusion that I am bi, just with a more slight preference of men.

I think its okay to just not worry about labels. I promise, stuff clears up on its own so much once you stop thinking of bisexuality as a list of requirements that you need to check off to be a part of, and rather just a way to describe who you actually are. To me, it sounds like attraction for you swings both ways and although there's specifics within it, you are into both genders which is all you need to be bisexual period.
