I'm 6'2, I got big bear-paw-hands, "longish" boy haircut, square glasses, a "relatively" deep voice. I move like a bloke, I talk like a bloke, I carry myself like a bloke...
And I do believe I "may" have passed "once" when talking to a girl with a learning disability.
So no, I don't pass worth dirt.
Even if my voice is fairly low "for a girl" it's still a girl's voice.
Even if I'm tall, I'm still soft and feminine.
Even if I move like a bloke, people presume, at best, that I'm just a tomboy.
I've stopped caring.
