god it feels good to even type that. For some reason, recently, i've just found myself drifting away from liking guys. At this point I'm not even sure that I like them anymore, at all. Sure, I love my guy friends, but where previously I'd look at a guy and think, "he's hot, i'd love to date him" it's now just "oh, he's hot." End of story. It feels damn good even typing that i think I'm a lesbian. Wow.
i am in the exact same situation, thought i was bisexual for a long time but then realized i have no real connection with guys other than their looks and when i had my first experience kissing a girl it was so much different to kissing guys. someone gave me this advice, in if you are question whether you are lesbian or bisexual, go along with being fully into girls for a week as in checking them out and that kind of stuff (not in a creepy way of course haha) and see how it feels
