I'm honestly not sure how to answer that question. xD I've been rather confused about my sexuality for a while now. At first I thought I was straight, then bi, then a lesbian, then bi again, and on and on and on. Right now I'm just unsure. I know for a fact that I'm attracted to men, but I don't know if I'm attracted to women. I know I used to feel that I was, but I'm not sure if I'm actually just straight or if I'm bi and currently am mainly into men (I used to be mainly into women, too). My closest guess would be that I'm bi, but I'm not 100% sure. I don't know if my feelings for women in the past were mostly due to my past feelings of gender confusion, which was likely caused or at least heavily influenced by my PCOS. (Note: If you don't know what PCOS is, it's something women can get that involves getting excess male hormones, which can cause things like growing a beard. I've had it since I was a teenager and while I no longer feel like I'm the opposite gender, I still have to deal with facial hair growth and such, which is irritating. I also have a rather deep voice for a female.)
Edit: Just for clarification, I'm not saying that I think you have to be masculine to like women. I'm just saying that I wonder if my gender confusion personally made me confused about my sexuality in the past. I don't mean to offend anyone.
