My balls are actually a little larger than average, but my damn scrotum almost never relaxes. Maybe some stretching would help. It would be nice to have them swinging freely, but most of the time they're kept up high and tight, as if to avoid danger. (Maybe it's safer that way.)
If it's 110 degrees, my air conditioning doesn't work, and I just got out of a hot shower, they hang almost below the head of my dick and it feels nice. Otherwise, they're practically in contact with my prostate and it's as if they're not even there.
Anyway, take a look.
