I never played with barbies though. I wasn't the three year old asking when my genitals would fall off or whatever. I didn't fit those stereotypes.
How it manifested in me was that I never got along with the guys. I never really was interested in being particularly dudeish, and the thought actually repelled me.
And when I had puberty, it just felt wrong. I felt like I was supposed to be different, on a level deeper than my consciousness. Like it viscerally was wrong for me. But I didn't tell anyone, because I knew I wasn't supposed to feel that way and I should just "man up" or whatever.
