A penis pump is such a useful tool. The cylinder creates a vacuum and sucks your penis upwards. You’ll feel intense pulling while in the cylinder. Some guys like this for masturbation. You will look bigger inside the penis pump as well, but understand that it is fleeting, as the length is temporary. Place a cock ring at base of pump, then slide the pump over your penis.  Voila!  That vacuum seal is created and you’ve created a firm erection.  Now just roll the ring off onto your penis and release the valve on the pump. Pro tip: use a water-based lubricant to create a better seal between your skin and the penis pump. We suggest CalExotics or Vacuum Erection System, both found in our Toronto sex shop or online sex store.
