I can still remember the first time I masturbated. I must have been about 13. I was in bed one night. I knew it was private and I wouldn't get interrupted. I’d gone to bed wearing only my PJ bottoms. After a while I was conscious that I was hard. Strangely I can’t remember being hard before this but I guess I must have been. Anyway this particular night I got totally naked and started to rub my cock. The feeling was incredible. I remember it seemed wild to be naked and stroking my cock. As the feelings inside me built up I continued stroking until some semen shot out. I knew that it was semen and so excited to know I was becoming a man. I was fascinated with it. Running my fingers through it on my belly, feeling it, smelling it and touching it to my tongue. I tried it again the following night and then again. Those first few orgasms were special to me. I also remember that after that first time I started sleeping naked, which I still do to this day.
I remember that a couple of weeks later I had my first wank with someone. The girl who lived next door was about my age and she used to come round sometimes to my house after school so we could do our homework together. We usually had the house to ourselves because my parents came home late from work. One night I just had a pair of shorts and a t-shirt on and I think she must have noticed that my cock was hard. Out of the blue she asked me if I would take off my clothes so she could "learn something about boys." After some hesitation, I decided to go ahead. I could feel my heart pounding as she watched me undress. I felt embarrassed to know she was seeing me naked, but I was also highly aroused. She left her clothes on though. My cock was definitely erect and she stared at it for what seemed like an eternity. Then she began touching it lightly, first the head, then down the shaft. As she continued caressing and exploring, I could feel the tension building up. Finally, semen began squirting from my cock, and I couldn't stop it. She seemed shocked, and she stopped touching me right away, although she continued watching the squirting. When I was finished, she said, "What happened? Are you OK?" The next night when she came round after school, she said she had told her older sister what we had done, and her sister had told her that it was a normal experience for boys to have. Her sister also told her how to properly masturbate a boy's penis. She asked if we could try it once more, but this time, she asked me lie down on my bed. Again, I was completely nude, and she was wearing her clothes. She knelt between my legs and held my cock with her thumb and index finger, moving up and down slowly until it began squirting. This time, she continued holding it until I finished.
We repeated this a few times until she moved away. She never let me touch her, but as she became more comfortable with me, she began masturbating me with her top off, and once she even took all of her clothes off. For the first time, I got to see a girl completely naked!
I think these experiences probably laid down my liking for being naked in front of others and for showing off my cock.
