There are many methods to enlarge men’s penis. One of them is penis pump or penis extender. Penis pump is a cylinder that is fitted over the penis to create suction. This is how it works. As small amounts of stress are applied to the penis body, skin cells are broken down and forced to regenerate. During this same process the internal cavities of the penis body are forced to expand, allow for more blood circulation and increase overall penis size.

That explanation will answer the question “do penis enlargement pumps really work?” When you use penis pump, you’d better use cock rings. It is fitted on the open end of the cylinder, and then an erection is created by pumping. You should push the ring by your hand to the base of the erect penis before releasing the vacuum. You can add personal lubricant too. It will make it easier to slide the ring off the cylinder, and later to remove the ring.
