While you may see an improvement in your erections from this technique, don’t expect a huge size boost. Men who had STIM shots gained only about .2 inches in length and girth per injection, and results typically last just two to three months. But repeated treatments could expand the vessels and tissues in your penis and provide longer-lasting results over time.
Ready to try it for yourself? Here's how to do it: Squeeze the muscles that you would use to stop the stream of urine and hold the contraction for 1 to 2 seconds (concentrate on only using your pelvic muscles, and not your glutes, thigh, or hip muscles). Release. Repeat 30 times, resting one minute when you're finished. Perform 3 sets, 3 to 4 times a week.
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.
