Learned on my own. - Around age 8 or 9 my penis started getting more sensitive to the touch than normal, when it got hard, while receiving or holding an enema. About the same time, after climbing a tree or rope while sliding down, it made my penis get hard and tingly, feeling so good, I almost fell a couple of times. So, I started rubbing my penis in bed at night, when it got hard, looking to recreate the tingling feelings that felt so good. The first or second time I did it, I got the same tingling feeling I got while sliding down a tree or rope. Shortly afterwards while talking a shower, I discovered that if I inserted the emema nozzle in my anus, from the enema bag that always hung in the shower, while rubbing my penis, it made the tingling feel two or three times stronger, than without it. I didn’t understand at the time, what the feelings were all about. All I knew was that, it was fun and felt real good. However, by the time they turned from dry to wet around age 12 or 13, I understood what they were about, and the rest is history.
Many years later, while staying with my nieces kids in the evening, when their parents went out to dinner or a movie. I kept their parents routine of giving them a bath together, before putting them to bed. I first observed their daughter at age four, while playing in the bathtub with her older brother, rubbing the top of her vagina, and the more she rubbed the more she giggled. I informed her mother about my observations, and she said, “she started doing that between age two and three, and it’s perfectly normal for little girls. Just, don’t pay any attention to it.”
