Here is an article about a penis enlargement exercise from www.penislessons.com:
Jelqing otherwise known as milking is a penis enlargement technique that involves using ones own hand to stimulate tissue growth in the penis by forcing blood through it. The jelq is one of the most reliable and safest methods of increasing penis size and does not require any special devices or need to spend heaps of money.
The basic principal behind jelqing is to force blood from the base of the penis to the tip in a single stroking motion. While in a semi-erect state grip the penis in an OK style with your thumb and fore finger and gently squeeze from the base to the glans of the penis. Continue this motion but alternate between each hand on every stroke, each stroke should take no longer then three seconds.
