Chopsticks

With your dominant masturbation hand, spread your index and middle fingers as if they were chopsticks (or the "peace" sign, for you folks who remember the '60s). Orient your hand so your palm is facing you; the "chopsticks" should be pointing to the left if you're using your right hand. Insert your penis between the fingers so your index finger is on the underside of the penis (the site facing up, or toward you're feet, if you're lying on your back) with the middle finger on the top. Next, squeeze the "chopsticks" together and move them rapidly up and down your penis. Your index finger does the important job of stimulating the sensitive underside of the penis, while the middle finger produces additional friction on the top. Lube is optional when doing this; in fact, no lube, or very little, intensifies the skin-on-skin feeling. This is a very simple technique that produces great results. It may even be more pleasurable for men who can draw out their orgasms.
