Even in reputable studies, the statistical average varies, US median is about 5.5 inch according to the biggest study (1661 sexually active men) we could find by the well known Journal of Sexual Medicine. Most men have an erect size between 5 and 6 inch, so below 5 inch can be considered small. This data matches my own long term experiences as an andrologist. Don’t be fooled by the penis sizes you often see in adult movies, all actors are selected individuals far above the average size. These movies certainly don’t depict any statistical average and also use visual tricks to make the manhood of the male actors appear even larger. Nevertheless, many men ask themselves how to get a bigger penis the natural way, without any unnecessary risks and dangers.
• Exercise counts. Exercise improves arterial health, allowing more blood into the penis. But exercising the penis itself is pointless. The sex media sometimes refer to the penis as the “love muscle,” implying that like the biceps, certain exercises can buff it up. But there are different kinds of muscle tissue. The penis contains smooth muscle, not the kind that gets bigger with exercise. Lose the big belly, because a big belly encroaches on the base of the penis, making the organ look smaller. Lose abdominal fat, and your penis looks larger.
Lengthening the penis. The most common procedure is to cut the ligament that connects the penis to the pelvic bone. This allows a little more of the shaft -- on average less than an inch -- to become visible outside the body. It's not really lengthening the penis so much as revealing more of what's usually hidden. To prevent the ligament from reattaching, a guy would need weights or stretching devices daily for about six months.
