Ever wanted to be a boy instead of a girl?

I'm not sure why I feel this way but have you ever felt like you wernt born in the right body? I can't help but think why was I born a girl? Why couldn't I have been a boy? I am indeed bi-sexual but I don't think that's what brings up these thoughts. I'm not classified as pretty really more of a average teenager I'm more of an outsider actually if you want to get technical. Im just not interested in the whole fashion scene or the flirty behavior everyone else seems capable of. Personally I think of my classmates as clones. I know it sounds stereotypical but that's what they all act like! Have any of you ever felt this way?
