I feel the same way as you, and am beginning my own journey. I have often seen male things and thought, "That's not me." I remember, when I was at school, and the teachers would say, "Boys do this and girls do this," I would think, "Well, I don't want to do that," and struggle and be unhappy. I remember, when I was in Year Four, we had a morning run before class, and the teacher sent the boys out first and then the girls came after and a boy said, "Hurry, everybody! We're getting girl bombarded." I actually slowed down. Another boy used to call me "Sissy."
