A little change of speed from whats been said, but squeeze a big portion of icy hot into your palm and stroke as fast and hard as you can until the burn becomes painful, and if u use any water or wet rag to wipe off, it has to be almost uncomfortably warm water. Try to keep the icy hot off your balls. If you do this right itll be sore for a while, candle wax may be fun to follow.
