I had my first experience in a pool at the jets. I'd never done anything before (12 yrs old) and a friend told me to try.
I was too embarressed to do it with him, so one evening I sneeked out to the pool (the pool light was off) and removed my suit. Stuck my dick against the jet and had about ten minutes of continous orgasm. I have never been able to reproduce the feeling. As a matter of fact, I noticed severe pain the next day trying to pee (I think the chlorine burned my tube).
Subsequent attempts (in adulthood) to repeat this intense experience only resulted in an extended duration masturbation session. I got off alright but it was nothing like the original. I think two things combined for the first one: 1) the water pressure running up my uretha and pulsing against the inside of my dick and 2) my inability ot ejaculate. Since I've matured, my dick grew and I don't think I'm able to get the same pressure. But what a wonderful memory.
