I thought something was wrong so I showed my mom. I would like to hear from others with similar experiences.
Like all little boys I would play with my cock in bed after my mom tucked me in. When I was seven-years-old I began the ritual of quietly climbing out of bed, pulling down my pyjamas and pulling up and down on the skin of my cock until it felt really good, and I couldn't do it anymore from exhaustion (I was having an orgasm but I didn't know it).
One night, I was going through my routine when all of a sudden, as I was enjoying an orgasm, my cock released a liquid substance from inside my erection. I thought it was pee so I cleaned it up and went back to bed. The next night it happened again and I thought maybe something was wrong with me so I went out and told my mom what had happened. She said that tomorrow night, before I go to bed, I can show her what I'm doing and she can see what's happening. That night we went into my room and my mom brought a box of tissues.
I pulled down my pyjamas and started playing with my cock in front of my mom. I rapidly beat up and down on my cock until I reached my climax and a bunch of liquid goo squirted out from my erection. My mom sat me down and explained that what was happening was normal, that I was having an orgasm, and that the liquid goo was sperm for making babies. She told me it's OK to masturbate in private but to use these tissues instead of cumming on the carpet. I never spoke to my mom again about our little secret but she always made sure I had plenty of tissues in my room.
