I've always answered girl to anyone who asked my gender as a kid, when I got to grade school I actually started thinking of it. Girl was the gender I was assigned, so I never really payed attention to it. I would just say "I'm a girl". This is probably why it took me a long time to figure out my gender, because I was assigned with girl and never thought of it. I've always just been me.
But what does gender even feel like though????!!!
