Just read some interesting stuff about ball stretching. When engaging in stretching one must measure the circumference of the nutsack to find the suitable diameter weight. But as I was reading I thought we know everthing about penis size both length and circumference but is there information regarding the average ballSACK size especially about circumferece and diamater? To find out I gentily pulled my sack out and with the measuring tape tight (not too tight around the sack). I measured it ABOVE my balls. My circumference of my nutsack was: 6.29 inch so my diameter was 2.00 inch. Could I get some other measurements from other people? Interesting to see what would be the results.
