I matured sexually very young. The erections happened every night in bed, and kept me awake. Wet dreams were a constant companion. I was very naive, and did not know about masturbation. When I was 13 my friend told me about masturbation while we were camping out.
The next day I was in the bathroom. A raging, throbbing boner swelled up. I remembered that my friend told me that my hand would simulate sex. I started stroking my erect member slowly at first. Then faster and faster. The feelings were wonderful. As I stroked for the next fifteen minutes or so the feelings were simple elation. My friend hadn't told me what happened at the end. Maybe because he was younger than I he simply had dry orgasms.
After about twenty minutes my penis began to spasm and squirt white gobs of semen everywhere. What an amazing surprise for a naive, sheltered oldest child in the family. Later that evening I tried masturbating again in bed. Again my mind was blown by the feelings and ultimate release of orgasm and cumming in my underwear.
For 46 years now masturbation has been enjoyable to me. For nine years after I discovered it until I was married it was my only sexual release. For 37 years I have also enjoyed a very fulfilling sex life with my wife. What a gift my friend gave to me, although I probably would have discovered it on my own.
