The intensity of trauma that surrounded my finding orgasm began at age 11. If I emphasize how that experience damaged my relationship with my mother, I hope that doesn't make me a "mama's boy." She had given me "Growing Up" at age 10, so she knew I would begin to ask questions. I'd had sexual feelings in the 3rd grade but didn't know what they were. Shimmying up swing poles at recess made me a queer duck who would race to the swings and not take one.
I am in my early 50s, maturing in the mid and late 1950s (before the "sexual revolution"). I have been married for 30-plus years. I began masturbating at the age of 8 or 9 (about 4th grade). I did not discover this amazing pastime by myself; rather, I was introduced to it by 2 friends, both older (10 and 11). This started before I had begun to physically mature, so my penis was only about 2 inches long when erect. I used 2 hands, sliding up and down the shaft. Rapid pumping up and down would get me to orgasm. Orgasms were dry but they felt good, so I continued to masturbate.
