I remember having only two orgasms when I was younger. Both of them occurred in a pool. The experience that I most remember was being in a swimming class and having races at the end of the summer before family and friends to show how much we'd learned. Well... my little penis was tingling a bit that day in the water and it was somewhat of a distraction; however, when my turn came I splashed off the edge of the pool and swam as fast as I could. The return was to be on our backs and I remember, as I made my turn, that the tingling in my penis suddenly increased to a throbbing pleasure! I had felt that particular pleasure once before a few years back (in a pool!) and wondered what made it happen. The water? The chlorine? I really wanted to know! Now it was happening again and I slowly lost my position in the race. In fact, not only did I come in dead-last...I wasn't quite sure that I was going to make it! I was a good 20 seconds behind everyone else.
A few years later, my good friend came over to show me something very special that he had learned from an older boy. I wasn't surprised when he took out his penis and asked me to do the same. We had done some innocent sex-play before. Showing me how to stroke it, I followed his instructions and withing a few minutes I had an orgasm. Oh wow! What a revelation! I realized that I could have those wonderful sensations ANYTIME I WANTED!
I've been a regular masturbator (girlfriend or wife notwithstanding) for all of my life and the day that I discovered that an orgasm was something that I could control...well, it was the best day of my life!
