Clamping, Stretching, and Hanging
Clamping is a technique that uses a constricting device, such as a shoe string, cable clamp, or a tight cock ring. The clamp is firmly tied, clamped, or put, respectively, on the base of the erect penis while "edgeing" (extended masturbation) with a firmly erect penis. Extreme caution should be used to prevent permanent damage to the tissue. Use of a metal cock ring is not advised because trapped blood engorging the penis can make it impossible to remove.
Stretching consists of attaching a penis stretcher or "extender" device to the penis for set periods of time. The device exerts a constant traction on the penis, which, in theory, lengthens and widens the penis. The traction supposedly causes the cells in the penis to "split" and then reform and expand. In 2002 a study published in the International Journal of Impotence Research concluded that penis extender devices are effective at elongating the penis and furthermore the increases in length correlate with the amount of time the device is worn. A similar study conducted by Paolo Gontero of the University of Turin was published in 2009 in the British Journal of Urology
Hanging is perhaps the oldest self-applied method of penis enlargement, with evidence suggesting it was practiced by certain African tribes as long as 2,000 years ago. Weight hanging consists of attaching a device (usually a rope or a strap) that grips the glans or just behind the glans and allows a weight to be suspended for a specific amount of time. Then a conscious effort is made to exercise the penis by raising the weight in repetitions (lasting no more than 5 to 10 minutes at a time) starting with the smallest and lightest weight 1/16 pound to the heaviest usually 1/4 pound or more, to increase the strength and stamina as well as elongation of the penis.
One must be completely healed after circumcision before attempting hanging. Weight hanging, however, can also carry serious risks, which include nerve damage, chronic pain, scarring and impotence. The potential of these risk is dramatically increased if the patient is not directly trained by a qualified Certified Therapist. The idea behind weight hanging is to stretch the Tunica Albuginea and other various tissues of the penis. The general effect is to elongate the penis, although widening can also occur.
Hanging carries additional health risks due to the restriction of blood flow to the glans, including possible erectile disfunction. Tribes with male practitioners of weight hanging, usually results in the men being impotent, although urine is still able to pass through.
