Undecided Question

How can I be happy that I am a girl?

I apologize for… not knowing what category to put this in… I know this is a strange question, but I need advice. Please don't say anything rude… ):

I just do not feel happy and comfortable in my own skin. I always felt more like a boy than a girl, and more masculine for some reason. It does not help that none of my heroes are women, and I look up to all these men (ex. the beatles)… I want to become a musician and a singer someday, but I feel like it won't be the same because I am a woman. Boys get more attention, and fans, and just seem to have more fun than girls… I'm attracted to guys, of course. I'm not at all attracted to girls, but I just wish I was a guy. But I want to be happy with who I am… But I don't know how to feel more confident.

I guess I feel like if I was a guy life would be easier for me. Never having to deal with getting pregnant or having a period. They don't have to care about how they look or anything really… It's just feels unfair to me…………… Advice, please? I'm just a fifteen year old girl struggling with her… everything. ):
