Foreskin Vibrations

Get an erection, peel down the skin, and stretch the index finger and thumb of your right hand (or left if you're left-handed), trying to get them as far away from each other as you can. You have a curve between these two fingers. Put it directly under the ridge at the top of the glans (penis head), and wrap your thumb and index around the glans. You can then move your hand in a fashion that doesn't go over the ridge but doesn't go below, either – always touching, move your hand up and down very fast, creating a type of vibrating action. This is very effective – if done properly, it can create an orgasm faster than many other techniques.
