I thought I was a boy until I got into school. My parents made me wear T-shirts, shorts and had my hair cut short. I think they expected a boy when Mom was pregnant and bought boy's clothes.
I thought I was a boy too when I was a kid.. I had long hair but I thought they were mistaken (I didn't think I was pretty like other girls, therefore in my mind I was really a boy) o.O
@sir well, I met some boys at kindergarten. I tried to hang out with them, but for some reason they didn't wanted to. I asked them they pulled down their shorts. That's when I realized I'm a girl. Also, my brother was born around that period.
