Natural part of life
My parents used to send me every summer to a YMCA camp in the mountains. In those days only boys attended the YMCA camp. Our cabins slept about 15 of us plus one or two counsellors. These were the days when all men and boys were required to swim nude at the Y. It was also the days when the fad was to not wear briefs and to sleep in the nude.
One summer when I was 13 or 14, I had a lower bunk that was at a right angle to the counsellor's bed. He was probably 18 or 19, very stocky and very nude at night. His bed was under a window. Being that the outside pole light illuminated him from his chest to his ankles, I could see him vividly every night. Every night he seemed to spread his legs and masturbate. Being that he was so close, within five feet or so from me, I could see every detail. His hardon was thick. His pubic hair was a reddish blond like the rest of him.
I would usually hear him in the middle of the night jacking off. Sometimes he would jack off right after lights out. A few times he would jack off in the morning just before revalie for all to see. After he finished moaning, he would get up with his glistening hardon and a handful of semen and walk back to the john.
None of us thought it erotic. We just thought it was what young men do and we did the same. As the summer wore on, more and more of us would jack off as often as our leader. We campers talked about it, but we didn't do anything unusual like jack off each other. Nor did we jack off anywhere else except at night. (Except at the big falls that took half a day to hike up to. There some of us did jerk off on the river banks after swimming and lunch. Even then we followed our counsellor leaders.)
My experiences of masturbation were that it was just a normal and necessary part of being a man. I appreciated learning that during my younger years. It sure helped keep me in check until I got married. All that masturbating has helped my wife and I enjoy sex all that much more.
