I KNEW WHEN: my first orgasm be-came indelibly imprinted into my memory! At the age of 12, it began with “jokingly” inserting my cock into my enclosed hand because of the talk I heard boys my age spout-off. That happened once-in-a-while for several weeks (months?), no erection yet. One evening at shower time, I secreted a thick-and-sturdy glass bottle into the bathroom, because I wondered what would happen when I inserted my cock into it. I did what came naturally, I put it over my cock and began going up-and-down. My vision began to narrow, and I could unmistakably feel something inside my brain! It was a little scary actually. “What’s happening?!” I thought. Although I felt a little fear at how intense it was (prior to orgasm), something compelled me to continue! It was a buzzing in my head (something was in there doing something!), my vision now in a tunnel! My knees buckled and my cock spasmed. That was set for life!
