I got something better that will stimulate the economy

A tad more fun.

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
