Yes.
Mine have been caught in the zipper.
That's when I started wearing button fly.
Embarrassing story- I shaved my nether regions for the doctor check up before my vasectomy. I told the doctor to be prepared as I had gotten my sack caught in the electric razor and had taken a chunk out ( and by chunk I mean a quarter sized). His response was "Hell son don't do that, we have nurses that do it for you." I was hurt and a tad embarrassed but it did not hurt like my sack did.

Trains.
I was driving on some back roads in some small town that I had never traveled too before. I went over this run down train track (that had no signs or warning lights), and in my peripheral I saw a moving object. It was a train about 50 yards from me. The train blew its horn.
Every time I drive over train tracks now I start breathing heavier, get a little sweaty, and my scrotum shrivels up.
Tornado outbreaks. Granted, I was fortunate to not be in the area of the Super Outbreak of 2011, but living in Dixie Alley, I don't want to go through the fear and horror of it.
