The first signs that I was becoming aroused was feeling my balls churn.
I had been masturbating for two or three years before I began to ejaculate which happened the first time when I was thirteen. After that great milestone in my sexual journey, I noticed that the first sign that I was beginning to get horny was when I felt my balls churning and retracting. It was then that I began to have almost perpetual hard-ons. This was something that could and did happen wherever I happened to be, at school, at home, walking anywhere. Mental visions of girls tits, my hard pecker, previous cums, and conversations with friends about masturbation or other sex were enough to make my balls begin their stirring motion, and send me rushing to wherever I could jack off.
When I got my fist wrapped around my raging hard dick, my balls activity doubled. When I began stroking, they not only churned harder, but began moving apart. As I got near the point of no return, they were alongside the bottom of my penis shaft, and when I began to shoot off, they were up under my pubic mound in sockets behind my pubic hair. They stayed there for a few minutes after I finished coming. Anyone else have this experience?
