can i be a she/her femboy?

so ive been thinking about my gender a lot for the past few months, and im stuck on deciding if im a trans girl or a femboy. I really don't like being a boy, but calling myself a girl doesn't feel right... but whenever i get called a girl i feel really happy for some reason, and i wanna go by a different name because i hate my male name. Am i still valid? I'd like to have a girls body in the future. So is being a she/her femboy valid?
