I was involved in a mass-masturbation ritual(?) at a summer camp at the age of 13/14. We just started masturbating/playing with our penises for some reason. One kid came on someone else (not his face).
In kindergarten I liked to sit down and play close to seated kindergarten teachers so that the angle would allow me to look up their skirts. I think they knew and did nothing to prevent it.
Also in kindergarten I was able to stay overnight sometimes (slumber parties I guess), but once I had to pee and was afraid to go to the toilet at night, so I quietly climbed out of my sleeping bag, rolled over to someone else and peed on him.
In the morning everyone blamed the kid for wetting himself.
I was exposed to horror movies and porn (anal & doggy style) at a very young age, so I kinda thought sex = anal until 12 or so and because of the horror movies (cheap, disgusting shit where women would give birth to aliens and such) I was afraid to stay alone at home and was afraid to expose my back at most times, so I just walked around while rubbing my back on walls at home.
At the age of 5 or so I think I had a penis in my mouth and remember some other kid having my penis in his mouth.
