When I was about ten, I wanted to develop my pectoral muscles, having seen how they can look in comic books. I liked the look, and decided to work toward it.
I found that if I held my body weight on a set of parallel bars it worked the chest muscles quite hard, so in my bedroom one morning I created a similar set-up by using a chair back, and my desk, with me between them, holding myself above the ground as long as I could.
After half a minute my p**** went hard. Really hard. Maybe twenty seconds later and it was throbbing, and the head had swollen to twice its normal size, and was very pink. Then I felt I was going to pee, so I stopped and went to the toilet. I couldn’t pee, and gradually the urge to pee subsided, and my p**** de-tumesced, so I went back to doing the exercise.
This time the hardness and swelling started again immediately, and the urge to pee quickly followed, and I just decided to push through it, and hold my pee as best I could.
At that point I had my first o*****. I guess I was too young to make s****, but the spasms were intense, and a few drops of pre-c** shot out and hit the wall in front of me.
The feeling was both incredibly enjoyable, and scary: I was worried I’d done some damage.
The worry didn’t last long enough to stop me doing it again pretty much straight away, and again later that day.
I did this for about 3 years before I had my first o***** that produced actual s****, and it became messy, so I just stopped, cold turkey, and didn’t think any more about it till I had a w******** a few nights later.
