When I was about 10 yrs old I caught my dick in my trouser zip, my parents spent about an hour trying to free it I was screaming my head off, I eventually was taken to the doctor who freed it in 2 seconds by pulling the zip back UP my parents had been trying to pull it down I still have nightmares about it
Just remember guys if it ever happens to you pull it up not down.
