There used to be a stereotype about old men that would blowdry their balls in open view of everyone and it really was true. They'd also start conversations with everyone while doing it like it was the most normal thing in the world.

Tbh, it is / should be normal. They're just genitals, you've got em too, there's no reason to make it weird. I know wrinkly saggy old dude balls aren't pretty, but neither are wrinkly saggy old dude jowls and you're not gonna expect him to cover those up
