I can confirm that things are pretty sensitive at least. You have to be very careful while shaving and then I genuinely can't have sex on the same day I shave the bits without risking horrendous irritation. I don't even know how someone would go about waxing testicles with how stretchy the skin is though so that guy is probably a wizard.

I had always assumed it was just a few pervs ruining it for everyone though too. The few times I've tried to go for professional waxing I've been told chest and back only - no pubic area at all. Probably a bit of column A and B because I suppose.
