I've had a dirty mind since early childhood, iin?
My first memories are all about me doing something naughty with my pee, poop, boogers, spit... or doing something perverted to other kids. Most of it was because I thought it was funny or wanted to get a reaction. I also swung a rope swing at a toddlers face and bloodied him up pretty good. I was only like a year older than him, though.
