Sometimes when I've been working out and get real horny I use my jock like this:
Take it off and put it on back to front. Now you have the two straps that normally go around your ass at the front. Cross them over your cock and balls and pull them tight so that your package is pushed forward and held real tight by the elastic. You'll find your cock harder and your balls tighter.
If you like ass play then the jock pouch, which is now in your ass crack, is ideal for helping to hold something in your ass. Do this in front of a mirror - it's a real turn on and great for increasing your jackin' pleasure. Enjoy! And let me know if you do.
