fecal balls
When a man's scrotum comes into contact with his own feces during the evacuation of his stool. Typically this man ignores the fecal matter and allows it to fester on his ball sack. Fecal balls are commonly discovered during sexual activity.
Maureen wasn't surprised to find Jim had fecal balls. He never had the best hygiene. Luckily Maureen has no limits and cleaned him.
