Thank you girls! This is getting deep! The "mechanism" of the discovery exists. Many many people never even approach breaking taboos. Most people. The sexual role definition is an ancient cultural determinent, even if it hasn't been bred into us through selective breeding. Some cultures accept cross-gender behaviors, but they don't produce offspring, hence it's not selected for. But, because of the flexibility of gender-questionable people, they often swing both ways and do breed. But it's gotta be recessive.

WHEN did I realize that my behavior was diametrically opposed to cultural norms? Very very early. My earliest memory is when I was six, wearing my mother's bra. I knew not to tell anyone.

Tess-Leigh,
I don't know what you are. How about "fem-boy?"

I love these discussions.
