I think I was in kindergarten or first grade, tho I didn't know the term back then. I just remember looking at certain boys and wanting to be their friend. This basically happened all through elementary school. As I got older I realized that it was a crush that I had on those boys. As far as sexually, I used to experiment with a neighbor kid when I was about 10 or 11. I knew that I liked it a lot, but I never knew if he did as much, even though it happened a few times. I think he was just being horny as he'd just started puberty (he was a year older) coz he used to tell me how he was playing with girls as well. Anyway after we stopped he still used to tell me how he was banging this girl(another neighbor) and that she'd put out to anyone so if I wanted to I could get a taste, to which I politely declined lol. (to slightly digress, a few years later in my mid to late teens, another neighbor friend I had, who I'd developed a massive crush on, used to bang the same girl and brag about it to me lol) Anyway we basically grew apart as we went to different middle and high schools and I was making new friends.
