This cylinder is 20", long with a diameter of 2¼". It is designed for two men to use simultaneously. Simply place a penis in each opening, attach our Basic or Deluxe Brass Hand Pump to the Air Pressure Valve, and enjoy pumping simultaneously. It comes with one Air Pressure Valve in the center.
This cylinder is intended for penis pumping as intense erotic massage and/or penis extension. Before we get into discussing the joys of penis pumping and the exceptional quality of this line of pumping products, we want to say: Proceed slowly and with care.
Excessive pumping can lead to discomfort and injury. When using pumps such as these, never proceed to the point where the suction causes pain. Stop when the penis is only slightly larger than its normal erect size. Be sure to read all the directions and warnings, and be conservative and cautious in using these devices.
When pumping, it is strongly suggested to not pump for more than 10 minutes a day. These new penis cylinders are hand crafted of the finest space-age polymers. Each crystal clear cylinder is built for comfort and the best vacuum seal without the use of awkward rubber gaskets. All expansion tubes are made of the thickest and strongest materials available. They include a quick connect/disconnect safety release valve that allows for disconnection from the expansion tube, while maintaining the exact pressure you have chosen.
How does cock pumping work? The penises are well lubricated and inserted into the tube. The pump is attached via the safety quick release airlock attachment. Upon pumping, a partial vacuum is created. Penis enlargement happens as your penises grow inside the tube.
While overzealous vacuum pumping does carry some risks, when done carefully it is a safe way to achieve mild penis enlargement. The most frequent problem is pumping the cock too hard and fast, stressing the penis. Too much pressure can cause temporary bruising of the penis, water blisters, red pinpricks etc.
Go slowly and increase the vacuum gradually over a long period of time. Medical Doctors have been using vacuum pumps to treat impotence for years. If done carefully, pumping is safer than surgical alternatives to penis enlargement.
Most men get greater increases in width than in length. The changes occur with long pumping sessions. It's difficult to predict how much of an increase in length will occur, but it's possible, while in the cylinder to gain as much as 2 inches or more in length. Generally the increases in girth will be larger, and longer lasting. Penis width is increased using wider cylinders. If you're more concerned about getting increases in length it is suggested that you buy a narrow cylinder. Your penis will get more of a pull in length in a long narrow cylinder. Pulling outward increases width.
Find Your Length: Optimum penis cylinder length is 2-3 inches longer than the maximum length of your erect penis. To measure, lay a ruler on top of the penis with the base nestled snugly against the point where the penis shaft meets the body.
Find Your Diameter: Penis enlargement cylinders are sized using the circumference (the distance around) the penis when erect. To measure the erect penis to use a string or shoelace/dental floss and wrap it loosely around the thickest part of the penis when erect. (Usually this position is very near the base, but some men find the area near the glans (just below the head) to be thicker. Mark the string where it comes together, lay the string out flat next to a ruler and measure the distance between the markings. This measurement is your penis circumference.
