I personally found that having the new female social role wound up shifting me more than the hormones. Like, at one point everyone began seeing me as only female, so now there's the shift in mentality where I find it weird to see other women as more than friends, unless they're super highly attractive.
I dated a lot of girls, but even then I'm hesitant to identify as bi simply because right now I just want to be with guys. Also wound up getting a boyfriend somehow, and it feels completely different in a way I'm really liking, so it's kind of hard looking back now. Things just feel better and more fun right now, for whatever reason, and where I never could imagine finding a guy attractive now I find myself feeling dazed and warm (in a really really good way) just from looking at him. It's a weird thing, life.
