The decline and fall of the athletic supporter

Go read this article in Slate to learn more than you ever wanted to know about this subject:

If you're a guy of a certain age, chances are you wouldn't think of hitting the gym without a jockstrap. For the uninitiated, the item known more formally as an "athletic supporter" consists of an elasticized waistband and leg straps connected to a pouch that holds the testicles close to the body. You women can think of it as a sports bra for a guy's balls.

Being of a "certain age", and also being a mechanic, I use stainless steel safety wire and duct tape.
