Also, losing weight, if you are over weight at all, will reduce the
fatty area above the
penis, bringing the
base further down, making the
actuall shaft longer. Gaining girth is a whole different ball game. Another thing, The Kinsey Institute states that the average adult penis when erect is between 5 and 7 inches long. So in that case you may not feel like you need to increase. Just be happy and healthy.
