Index-Pinky Scratch

The index-pinky scratch is a ball scratching technique that involves only using your index and pinky finger to scratch your ballsack. Using the hand that you pee with, you fold the middle & ring finger downwards, leaving only the index, pinky and thumb sticking out. Then you reach for the bottom of your ballsack and start dragging your index and pinky upwards, slowly and intensely. This method targets the itchy area much more effectively with needle-like precision. Note that this only works best with moderate-long nails.
I used the index-pinky scratch technique to soothe my itchy balls and have never felt better.
