Penis pump cylinders
A cylinder has its own internal dimensions, which are separate from the size of the outer housing. Those measurements and the product’s intended fit help you choose more usefully than a dramatic name on the packaging.

Intimate pumps use suction through a cup or cylinder designed for a particular area. This range includes more than penis pumps, so start with the body area the model is made for.
