All we need is a new terminology for "effeminate and feminine mind" that has nothing to do with being a girl or a boy. Being a girl or a boy is dependent on penis or vagina. Its because gender roles are so convoluted when it should just be "you have a penis or a vagina" and can act any amount of femanine or masculine as you want without judgement. But the very words masculine and femanine instill a sense of gender because we are so used to it. When the universe doesnt see it this way. Masculine and Femanine have no gender they are just a social mechanism for categorization of behavior to society around them. Even in nature you come across animals where the female half of the race is more masculine in actions than the male half. Masculine and Feminine can be attributed to "preditor and prey" except its not that extreme within society and humans. I wish i could think of a better word than Masculine but i dont like "dominant" either.
I think if you accept yourself then you would call yourself feminine if you felt girly (assuming you were a guy that was girly). If you want societys acceptance more (a whole bunch of people that you will never meet) then you will prolly care more about your drivers license saying "female" than calling yourself "girly". There is no need to say "my mind is feminine" on a license or ID, this is just for personal ego.
