Your feelings are valid and legitimate. Even if they are confused and unsure. I can't tell you who you are because you are the one experiencing your feelings and not me. You aren't inventing anything. If you end up deciding that you don't want to date men, but do want to date women then you're gay. Even if you have twinge around unavailable male celebrities who you aren't going to date in real life.

That said I'd suggest just dating whoever you feel like and not worrying about any labels for now. If you end up finding only women hot then that's valid. If there's a dude who comes along and gives you butterflies, that's also fine. Figure out labels later.
