I want to be a guy?????

Im a 14 year old girl, and all my life I have really wanted to be a guy. I don't feel uncomfortable in my body, but im really shy and don't have much self esteem and I have always thought, that if I were a guy, I wouldn't be shy and I would feel good about myself. When I was little I used to wear guy clothes, have short hair, and would refuse to wear a shirt at the beach or pool. I was like that until I was about 11. Then my mom forced me to start dressing and acting like a girl. I felt awkward at first but got use to it. I used to have crushes on guys, but I look back on them now and realize....they weren't crushes. I had my first crush on a GIRL in my class at school in 6th grade. The guys I thought I had crushes on, I really just wanted to BE them. I would always fantasize in my head of me being born as a boy rather than a girl. And I used to pray before I went to bed that when I wake up in the morning, I would be a boy. I used to put socks in my pants to make it seem like I had a penis... Why was I like this? I still wish I could be a guy because it would make things so much easier, especially since I like girls. Does anyone know whats wrong with me?
