Where I grew up, in a very conservative state, things like masturbation were not even talked about. It seems to me that Idaho might be a bit on the homophobic side. Also, for some reason, some people have the unhealthy attitude that if you masturbate you are gay, when obviously as many straight people masturbate as gays do. At least in southeastern Idaho, that is the attitude. I never did have shower experiences with other guys because no one ever took a shower in P.E. I don't know how other people pulled it off without smelling horrible, because I had a terrible time with B.O.
When did I start masturbating? The first time I ever tried it was when I was 15. Several weeks before I had my first session, I was about to take a shower, when I found some magazines in with all the towels. I at first thought they were my mother's women's magazines; I had often seen her put them there. How wrong I was! I took one out and opened it. I was presented with one of the top-shelf magazines for sale here in the U.K. Naturally, I had a good look through and noticed my penis to be erect (which wasn't unusual, because I'd been having lots of "wet dreams" at that age).
About 6 years ago, at the age of 12, I discovered the many joys of masturbation. It was a regular night, and I retired to the bathroom to take a bath before I went to bed. I liked to take long baths; sometimes I would even read in the bathtub, but most of the time I just relaxed and let my mind wander. I retracted my foreskin, as my father had instructed, to wash my penis and prevent infection. This time the feeling I had was unlike any other — somewhere between an unscratchable itch and a pleasant tickle. I continued to do this, and the odd sensation became stronger, and more pleasurable.
I'm not sure how old I was the first time I masturbated -- 10 or 11, I think. I hadn't started puberty yet, I know that much. I've always like to read, and one day I had run out of library books and was desperate so I was reading my mother's "MS" Magazine. There was an Ann Landers-type column, and some woman had written that when she was a little girl her mother caught her in the bathtub with the water running onto her clitoris. She was so upset that even as an adult she could take showers only.
