I agree you have to be tallish & no tits skeleton. But still it's easier for girls to look cool & like a beautiful boy, even more than actual boys.
And that's because facial feminine features are beautiful. Most beautiful young male models have "feminine features" and are capable of going androgynous if they wanted.
masculine features are disgusting facial hair aka facial pubic hair, squareish head silhouette, large Neanderthal foreheads, they also get old and ugly faster, oh yeah and male baldness! That SHIT also is x100 more common in male sex!
I was lucky and I got a mix of those features, so no baldness for me, no disgusting facial pubic hair or ugly, old, rugged face. I look youthful, ageless.
