Hi
I never really came to terms with my sexuality until my teens, but even before that I knew I was gay because I would have crushes on female cartoon characters and stuff, but never found the cartoon heros/princes appealing. I went through a period where I didn't want to be lesbian, but I got over that.
I don't feel I'm asexual because I do think about sex quite a bit, but sometimes my sex drive changes based on my mood and what meds I'm on.
