What is a Penis Pump and how does it work?

A cylinder is placed around the penis. A hose is connected to the pump which evacuates air from the cylinder. As the air is removed from the cylinder, the penis is pulled further into the cylinder and towards the walls of the cylinder, making the peniss larger. The pumps do have medical uses for men who suffer from impotency. Pumps can be used to obtain an erection, maintaining it erect with a cock ring, removing the pump to engage in sexual intercourse.

How to use A Penis Pump.

It is important to take it slow and gradual. If the pressure increases too rapidly it will cause bruising and pain.
If you do get any bruising, it will usually go away after a day or so. Do not pump until you are in pain. If you began to sense pain, release some of the pressure. Only Increase the pressure to highest level that you can maintain comfortably. Leave the pump on for a period of time. Some people watch TV, surf the net, etc. to help pass the time.
