In my opinion, not necessarily….and probably the answer is no.
Have you ever felt that you wanted to be a boy, and that you didn’t want to be a girl? I mean….not just being irritated by being a girl and seeing boys get more privileges because they are boys.
I’ve known many girls who were proud to be girls, yet liked sports, roughhousing, and other “guy” things. They also wanted boyfriends.
I like poetry and some other “feminine” things. I’m not the least bit effeminate, but somebody called me a “metrosexual” once. Even so, I am a man, and I’ve never wanted to be a woman.
