My dude, your ball hair lives inches away from your butthole, maybe not even that far depending on how saggy your balls are, how long your hairs are, and how supportive your underwear is. I promise you that nothing that's splashing onto your balls is any worse than what's already there.

It’s not that powerful of a jet of water. I mean, I’m sure there is some, but if you’re doing it right, only the parts you want to get wet are getting wet. Besides, the alternative is like using a paper towel to clean peanut butter from a shag carpet.
