My worst nut incident took place about 5 years ago. It all started when I was sitting on my surfboard out in the ocean, and I went to adjust the leash strap on my ankle. As I was leaning over to adjust it, I started losing my balance and somehow the board submerged, turned sideways, and then shot up full-force into my left testicle, smashing it between the rail of my board and my thigh. The throbbing never went away and eventually got worse for a week, so I had to go to the doctor. He thought I had a testicular torsion, so I went to a surgery center thinking I was going to lose my left nut that day. After they took an ultrasound of my nuts they said it wasn't a torsion, but they found some fluid (not semen) filling my nut. After that they basically told me to walk it off, but to this day my left nut is like 10x more sensitive than my right. Even a small tap leaves me reeling.
I've said it before but it deserves repeating, "Theres 3 guarantees in life, death, Fedor, and bitches be crazy" .
