Let's be honest, we all like the idea of having a bigger penis (what man doesn't?). With PUMPED penis pumps they can help give you instantly harder erections and a fatter penial shaft... plus they are great fun to play with, and should be in every man's sex toy collection. Regular use of a penis pump can result in increased sensitivity and temporary penis enlargement. Fun fact: Penis pumps were originally created to help people suffering from erectile dysfunction and as an alternative to Viagra!
