I'm always referred to one of the guys. Because I'm not the girl who gets all girled up to go out. And I usually don't flirt a lot I just act like one of the guys.
Girls look at me different and I need help on physical apprerence so I come across like a totally girl. Can you help me?

Don't worry about it. Be happy as the person you are. Personally, I live by this:
"I'd rather be hated for who I am, then be loved for who I am not."
