I am confused about my gender.. I think

So a few months maybe years ago (I don't quite remember) I started feeling like I wanted to be more masculine. I wanted to go around in boys clothing, I cut my hair short and I just wanted to LOOK like a boy, but I don't think I want to be a boy. I also want to dress feminine. But at the same time I do want to be a boy. It's complicated and hard to explain. Sometimes I just wish that I had two bodies. One male and one female. I am really confused about what this is and what I'm feeling. I am not good at explaining it.. Sorry. I just assume I am a girl, since that's what I've been told all my life. Has anyone ever bothered with this before? Does someone have a clue to what it could be?

I also think I'm pansexual, but I don't know if that has anything to do with this.
