When I was 8 years old, I went to a non-denominational Bible camp over the Summer.
There was only one phone on the property, and there were no available electronics. The cabins were pocked and separated, boys according to boys and girls according to girls. Every cabin had counselors who were around college age.
One night, things got very bizarre. The counselors in my cabin started mooning each other for some reason. They were being crass. Suddenly, one of them pulled out his penis and put it through a piece of cardboard, which had a prepared circle cut in it. Then another counselor produced a disposable camera and started taking pictures of the penis. They were both laughing hysterically. Afterward, the guy taking photographs showed some of the children his singular ball. (I didn't see it, but damn I wish I was making this up).
The next day, I informed one of the more pontificated counselors after crying myself to sleep the previous night.
Everyone who participated in those events was expelled from their respective colleges and expelled from the camp. Every one of them had a girlfriend, and none of them were sexually repressed other than the fact they were staying in a boys dorm.
It was really weird. Not sure if it can be considered abuse, but it was weird.
