Do any of you feel more confident in a masculine role?

I'm a girl who identifies as a girl, but I feel much more confident when I wear masculine clothes or act with a more masculine demeanour. I just feel like masculine "roles" fit me better, and I'm trying to gain muscle mass in the hopes of bulking up and looking less feminine, and I do also want to lose my curves. With that said, I don't hate or not accept my body. I don't think it's a matter of gender, really... Just kind of a matter of style.

What do you think?
