The Bathmate Hydro7 penis pump is designed to increase the size of your penis.

Compared to a normal penis pump, the Bathmate Hydro7 can create a much greater negative pressure around the penis as it is used in water.
How to use a Bathmate Hydro7 penis pump:

     Fill your Bathmate with water from the shower or bathtub.
     Put your hand under the bottom of your Bathmate to keep the water from flowing out of the valve.
     Place your penis in the Bathmate and press it towards your body to create a vacuum.
     Release the handle as soon as you feel there is enough vacuum and continue your shower.
     If you feel the vacuum loosen, pump again.
     After about 15 minutes, press the air escape valve and it will release from your penis.
