Like you, Headbang, my balls have dropped over the past few years. They used to stay close up at the base of my cock. Now they hang lower than my soft 7 incher. About 5 years ago, the swinging became noticible. It bothered me at first, but I have learned to like the swinging. Even with trousers on, I can feel my balls bouncing off my thigh as I walk. They roll between my thighs when climbing stairs. The swinging and smacking makes sex more fun.
