as penis enlargement surgery is for cosmetic purposes, it's unlikely to be available on the NHS. The most common technique involves cutting the ligament that attaches the penis to the pubic bone and performing a skin graft at the base of the penis to allow for the extra length. Professor Wylie says the surgery can result in an average gain in length to the flaccid penis of 2cm, but there will be no change to the size of the erect penis. Libomax Male Enhancement Jelqing is an exercise involving repeatedly pulling the flaccid penis using the thumb and index finger, with the aim of increasing erection size. The idea is that the pulling exercises will increase the blood capacity of the penis' erectile tissue, allegedly resulting in increased length and girth of the penis.
