Choosing your size:
To make sure you will get the right size of the pump for you, measure by wrapping string or dressmakers tape around the base of the shaft of your penis when erect. Divide that length by 3.142 and the result will be the diameter of your cylinder. If you choose the next nearest diameter larger it allows for expansion.
