My accidental orgasm occurred when I was 12 1/2 years old. I had already had sex education in the 7th grade so I thought I knew everything there was about sex. There was so much I didn't know. I thought that one or two sperm left a mans body during intercourse, and that the sperm would be large enough to see with the naked eye.
I decide one day that I was going to see what my sperm looked like. I thought that if I 'humped' the bottom of the bath tub I would get to see one. I was smart enough to rub my entire body with a bar of soap first so I would be able to slide by body against the bottom of the tub without hurting myself. I can remember starting the process and quickly becoming erect. I knew this was part of the process. I didn't know how long I would have to do rub my penis before I saw my sperm.
As I continued to rub my penis on the bottom of the tub, I remember thinking to myself how pleasurable the experience was, but I wasn't sure why I was feeling the way I was. The more I did it, the better it felt. I finally stopped because I got scared. I felt like I was going to have to pee.
Then I thought about it for some time. Nobody would ever know that I urinated in the tub. I start humping the bottom of the tub again and the sensation was there again almost instantly. It felt so good, and I couldn't stop. I kept on going, and it was so unbelieveable. I kept looking down at my penis and couldn't believe how big and erect it had become.
Finally there was relief from the pleasure, and it felt like it all came out. I was afraid to look down because I thought that I would see blood. My heart was still racing, and I was very much out of breath. I finally looked down and saw some white sticky fluid on and around my penis. I still didn't have a clue this was semen, and that there were millions of microscopic sperm in the substance. I remember feeling guilty and afraid at what had just happened. I told myself I would never do that again until I wanted to be a father. Well, that thought lasted about two days before I fell in love with the bottom of the bath tub.
I never told anybody about that experience until now. I wish the internet existed in the early 80s when I was first discovering the joys of masturbation. I thought that I was the only one who had ever experienced self pleasure.
