What is Penis Pump?
Penis pump is one of the most common ways men attempt to obtain instant erection. Penis pump is a simple device with a hollow tube where you can put your penis. On the top, it has a pump which sucks blood into the penis by creating a vacuum inside of the tube. The blood then gets caught in the penis by means of a rubber ring placed around the base. This ring emulates physiological veins constriction (please refer to Penis Erection Explained) and allows your penis to maintain its erection so you can make love without losing the erection.
