The first time that I recall masturbating was when I was about 4 years old. We were visiting with friends and I was sent upstairs to take a bath since it was nearly bedtime. I finished my bath and let the water run out. I noticed that I had an erection, which meant nothing to me at the time. But I put my hand on it and liked the sensation. I am uncircumcised, so I started examining my foreskin. I discovered it felt good when I pulled it back, so I started moving it back and forth. I guess I must have been so caught up in the moment and the pleasure that I kept on doing it for a long time.
