Obviously you get to choose your labels, but theres absolutely nothing wrong with being a tomboy and it certainly doesnt invalidate your identity, unless you feel it does. Some of the women i know and like the most are tomboys. I certainly dont view them as any less of a woman, although quite frankly i dont spend time thinking about peoples genders either.

Just do you! Being proud of who you are is great, but if you dont like who you are there are always options to change. If you had to describe how you want to be viewed, how would you go about it?
