I used to date a guy while I lived in Louisville who only had one nice sized ball.
He was a great guy but really didn't like the fact that he had only the one ball.
I moved away and after a couple of years I went back to visit friends and see folks I hadn't in a while. So I went over to the guys house just to see him again and the very first thing he did when I got to his house was whip out is junk to show me his new ball. He had about a year earlier he had a prosthetic inplant and was very excited to share it with me. It was a very good match to his natural ball and looked nice and felt pretty much the same.
