Jelqing exercises all work the same way--by forcing extra blood into your *****. To do this successfully, you must firmly grasp the circumference of your ***** at its base. Now, how do you know you have grasped "firmly" enough to allow blood to flow in and not allow blood to flow back out?A jelqing tutorial with pictures is a great help in showing just how "firm" your grasp should be. Jelq photos show you just where to grasp. They also give you an idea of how your ***** will appear as you continue with the exercise.
