I wonder if there is any correlation between what leg it's on, and whether you're right handed or left...
i've heard that one testicle hangs lower than the other. true with me, my left one is lower, so no room for my dick on that side. its just usually snuggles up all warm and cuddly in my mass of pubic hair.
Left it is. A LOT of 'lefties', here! I find it sort of just slides down that side of whatever pants I got on most easily.
