I remember the sensation of rubbing against things when I was young feeling good. From about 6 or 7. I liked it when it went stiff, even if it was tiny. I progressed from just rubbing to more conventional masturbating at about 8. I would hold it between 2 fingers and stroke. It felt nice. At about this time my mother would check my penis and foreskin to make sure it was clean, she would stand me on a mat after a bath and peel my foreskin back to check it. I remember my little pink glans popping out of the foreskin which at that age was quite tight still. (later, my foreskin would become very long and loose) At these inspections I sometimes would get erect as it felt nice to pull the foreskin back. My mother told me that erections were normal and so was the feeling of liking it when it was played with or rubbed. From then on masturbation was something I did and enjoyed even though the orgasms were dry. I remember the first orgasm feeling so nice and like I needed to pee but nothing came.
I was a very late developer so ejaculation came when I was 15. I was at boarding school from 11 and was teased badly about my size and inability to cum. But I joined in the masturbation games anyway.
When I ejaculated for the first time I was so happy and the orgasm was very deep and powerful. I had masturbated a day or so before and remember feeling it was wetter, the pre-cum seemed more and was a little milky. Then when masturbating at home in the bathroom I was standing over the bath and when the orgasm started I felt like I was going to pee, then a couple of drops of semen came out followed by a string of white cum that flew about 2 feet. That was followed by 4 or 5 amazing bursts of pleasure and cum. The next day I did it twice.
