I have been having erections for as long as I can remember, even before going to school. I also used to enjoy playing with them.
When I was about 13 us boys at school used to tease each other about masturbating and would give an up and clinched fist action. I didn't really know what it was about but one day while I was on the toilet and was playing with my erection I decided to experiment. I grabbed hold of my penis and began moving my hand up and down. The friction made things a bit uncomfortable but the pleasant sensation was a more powerful force so I continued. After a while it felt as though I was going to pee so I stopped. I couldn't figure it out because I had just had a pee. Mind you I wasn't too distressed because I enjoyed the feeling and thought it was a great way to bring on a pee. After the feeling settled I began again until I though I was about to pee and then stopped. I did this a few more times and was really enjoying myself when suddenly I lost control and my penis began to throb as a thick white liquid squirted out and splashed onto my stomach and chest. Boy, was I surprised and amazed.
