3. Pull the scrotum out again just as in exercise 1. Use the tips of all four fingers on the bottom side of the skin using both hands. Pull the hands along with the scrotum edges in opposite directions to make the stretch, grasping the scrotum between the finger tips and along the side of the thumbs and hands. This grasps and holds the entire length of the scrotum in both hands. Hold for about 45 seconds under the hot bath water or shower stream.
