How do you explain to your wife why you shave your balls?

Just like the way it feels.

My wife has not been around the guys for many moons

I can't tell you how many providers including a few girl friends that appreciate clean balls, shaving is even better. If you love play down there like I do, especially BLS then you better take time before an appointment to clean them as you would your mouth or shave your face. A public announcement for the benifit of all providers. Lol
