I dropped hot spicy gravy on my penis, the pee hole burned like hell for 2 days, I was only 6, and of course getting your penis skin stuck in the zipper. Then there was getting punched in the gut, falling face flat from a 12 ft roof, off a small hill in to a ditch on my bicycle, flipping over all the way down on my first day snow boarding and twisting my spine, falling off a tree house (25ft'ish) in the bushes below, getting hit by a motorbike. It's a long list you, just made me remember all that.
But none of that, none of that compares to the emotional trauma I went thru, when my 19yr old crush told me to stop trying to cup a feel until I have a bigger dick, who says that to an 8 year old.
