I have masturbated since I was five. I remember lying in bed playing with my little cock. As I am uncut I would slide my finger inside the foreskin and wiggle it around the head. I do not remember when I actually began to rub it in the usual manner, nor do I remember my first ejaculation. It was just something that happened.
Others on this site have written how they used to jack off with a friend or brother, but not me. Whenever I tried to bring up the subject with friends I was called queer and made fun of by boys who I knew for a fact also jacked off.
It was only once that a friend of my older brother just took out his cock and began to jack off in front of me. We had been swimming in a creek pool that was quite isolated. I was about thirteen and he was sixteen, so since I was jacking on a daily basis I just pushed my swimming suit down and joined him. It was done all so matter-of-factly that it seemed quite normal. As I remember there was no great passion in the act, just a normal release of tension. We did it twice after that but never jacked each other. Even though he had an eight inch long cock to my six and a half inches I was neither excited or turned on by the sight of it. Jacking together was just something that two normal teens did.
He was the only male I ever jacked or ever wanted to jack with since then. I have not seen him for over forty years.
