Penis pumps are a popular sexual accessory commonly used to enhance the length and girth of the penis. They can also help the user achieve an erection, and some physicians recommend pumps as a treatment for erectile dysfunction.

A typical pump consists of an tube (or “chamber”) made out of ABS plastic or another body-safe material. The user inserts himself into the tube, and a band made from plastic, rubber, or silicone creates an airtight seal around the base of the penis. A pump removes air from the tube, increasing the pressure. This enhances blood flow and causes an erection (if the user didn’t already have an erection, of course). Many pumps also have a gauge which shows the pressure levels in the chamber.

Some pumps user water instead of air, but the mechanism of action is essentially the same. Pumps can allow for a substantial – but temporary – expansion of the blood vessels, increasing the size of the user’s erection. They’re excellent sexual aids, and they can give guys more confidence by temporarily enhancing penis size.

So, are penis pumps safe? When used correctly, they won’t permanently damage the nerve endings or soft tissues of the penis. While the pressure is substantial, it’s applied evenly throughout the penis.

With that being said, any device that affects blood flow carries some risks. You should check with your physician before using a penis pump if you are diabetic, if you have any blood disorders, or if you take blood-thinning medications. Otherwise, the health risks are negligible if you use your pump correctly.

Some common side effects associated with penis pumps occur when the user applies too much pressure too quickly. Symptoms include:

Bruising – This can occur at the constriction band or throughout the penis. The penis might turn slightly brown or blue, but often the user doesn’t notice the bruising until the pump is removed.

Petechiae – Characterized by small red dots, petechiae is bleeding that occurs under the surface of the skin. It typically heals on its own within several days.

Pain During Ejaculation or Urination – Usually caused by pressure around the constriction band. See a physician if the pain is substantial or if it persists for more than a day. If you feel slight pain from the constriction band, you may be able to improve your comfort by applying a little water-based lubricant before you use your pump.

Temporary Numbness – This occurs when a pump restricts blood flow. It normally subsides within a few minutes of removing the pump. If your penis feels numb more than 20 minutes after you release the pressure, you should contact a physician.

The most serious side effect associated with penis pumps is priapism – a painful condition that occurs when blood cannot flow out of the penis. If your erection does not go away within several hours after using a penis pump, you should seek emergency medical attention. This is uncommon, however, because it usually occurs when a pump is left on for an extended period of time.

If you purchase a high-quality penis pump and you don’t have a history of blood disorders, you can safely use your equipment without worrying about how it will affect your body. To stay safe, look for a pump with a gauge and increase the pressure very gradually. Release the safety valve immediately if you feel discomfort or pain. Penis pumps are fun, effective, and completely safe, provided that you take your time and don’t try to create too much pressure at first.
