In the summer between fifth and sixth grade, I turned 11. This story occurred sometime that summer, but I don't know if it was before or after my birthday.
I was on my front porch with another boy from the neighborhood who was much younger than me. A classmate, Bert, came down the street and stopped on my porch. Bert had been knew to my school the previous year because his school had closed. He was one of the 'bad kids,' while I was a nerdy teacher's pet. Looking back, I would probably call him mischievous rather than 'bad' today. Anyway, the point is that we were quite different. Eventually, he asked us if we ever got boners. I was so naive that I didn't even know what that was! He explained that 'It's when your dick sticks straight up.' (Ooooh...he said a bad word!) Of course I had, but I didn't really know what it was. Bert talked about how annoying it was, and that if you were trying to get rid of it or do anything about it 'people would think you're playing with yourself.' It ended there.
That night, I started thinking about boners and playing with myself, something I had never done. I just reached down into my underwear and started playing with my penis. I assume I eventually just took the underwear off. The technique I used was quite unusual, but I'll describe that later. Eventually...WOW! What was that?! My penis sort of hurt but it fealt really good too. I had no idea what it was. I tried it again the next night, and the same great feeling occurred. I was addicted. It wasn't long before something came out when I finished, and I didn't quite understand that either. It's funny that I knew it wouldn't be appropriate to ask anyone about it.
Over 18 years later, I'm still doing it and loving it!
