Yes I seem to have developed a real testicle fetish. as I got older my balls began to hang lower and my wife began to grab hold of them more during sex. She would pull, squeeze and give them a gentle slap, all in a playfull way but demonstrating that she was in charge. balls are amazingly sensitive and allthough there was some pain it was deeply erotic. I love it, but nothing too serius, I definitly could not take a kick to the balls, even a gentle one so ballbusting as such is out.
The result of this fetish is that I now stretch my balls down by wearing weights, pumping and hand stretching so that I hang nice and low to make it easy for my wife to get hold of my balls. And hopefully to encourage her to indulge.
cirus.
