I'll never forget it...I was 13.
Even to this day, I've never had a wet dream but I discovered that rubbing a sock on my cockhead produced an amazing feeling. I graduated into folding the sock over the head into a tube and grinding my hips to fuck it. One day, the sensation was extra intense and I kept pumping and pumping in the sock.
I didn't know what was going to happen, but there was this feeling that made me keep going and going. All of a sudden, in the heat of passion, I came. OH MY GOSH! Streams of "white stuff" shot out everywhere; all over my belly and hands and the sock.
I remember saying outloud, "Oh my gosh, I can make babies!" Of course I had no formal sex training and knew nothing about coming -- I used to think that you pissed in a woman since I read in a dirty magazine that a woman said, "a warm sensation filled my pussy".
Since I'm a gay man, I won't have children, but I hope you parents out there tell your kids a bit more about sex than my parents did me and my siblings. My Mother told my Sisters about Menstruation by putting a box of Stayfree MaxiPads in their closet.
