I long wondered whether most teens learned jo techniques from scout camps. Once after delivering my son and his friend to the camp, I noticed that the scoutmaster's pickup windows were dangerously dusty inside and out. I had time to clean them before I started my 110 mile trip home. I don't know whether he found out who cleaned them, but about 6 years later, I bought his old truck. I went to clean it up for myself and discovered over 100 dried up semen deposits on the door upholstery. The height was what you'd expect from a 13 year old standing next to the open door.
Check out your son's scoutmaster's pickup after a campout.
The evidence is that jacking off happened not only every campout, but by most boys there. I suspect that if leadership knew about it, they were allowing them to sow their wild oats before they were old enough to keep it more private.
