Back when we lived in the countryside I'd sometimes go for walks in the fields and there was one which had a very rikety tunstyle that you had to climb over it was built around a barbed wire fence. 

Anyway one day while climbing over it the wood gave way as it was rotted and I fell onto the barbed wire it cut through my trousers, my underwear and my scrotum. I'm not entirely clear on how I made it home but I passed out from blood loss several times and an ambulance was needed, at the hospital they cut off my clothes and I could see my testes dangling out of the tear in my scrotum, rather than be horrified I was fascinated, they gave me a sedative and when I woke up I was sticthed back together and was kept in for 10 days, they had to give me several blood transfusions, tetanus shot and at the end of it I had to give a semen sample to see if everything still worked. 

The scar sometimes drives me mad usually on very damp days or when the weather changes.
