Don't bother with stretching or weight-hanging. These two techniques are said to lengthen the penis, and in some cases they do. But the longer it gets, the thinner it gets; both methods cause the penis to lose girth as it stretches out. The only time to use a penis stretcher is after having surgery, when it's necessary to prevent the accumulation of scar tissue.
Again, holding the glans, pull your penis away from your body. Then place the thumb of your other hand on your shaft, at the base of your penis, and press down with your thumb while lifting up with your other hand. Hold for a 10 count. Repeat this exercise to the right and to the left, placing your thumb on alternate sides of your penis in order to create tension. Continue stretching — alternating among up, right and left, but never down — for five minutes. Repeat once or twice per day.
Consider taking L-arginine. This is an amino acid that leads to increased blood flow, helping the penis get larger during an erection. A study conducted at Tel Aviv University showed that some men experienced improvements after taking the supplement for 6 weeks. It's available in natural food stores, and the recommended dose is 1 gram (0.035 oz) three times a day.
The side effects of lengthening surgeries are numerous and include infections, nerve damage, reduced sensitivity, and difficulty getting an erection. Perhaps most disturbing, scarring can leave you with a penis that's shorter than what you started with. Widening the penis is even more controversial. Side effects can be unsightly -- a lumpy, bumpy, uneven penis.
