Penis pumps work by expanding the corpora cavernosa so that they hold more blood - making the penis thicker. At the same time, they stretch the length of the penis making it longer.

What is vacuum penis pumping?

A clear, usually acrylic cylinder is placed around the penis. At the end of the cylinder a hose is connected to either a hand pump, or an electric pump, which evacuates air from the cylinder. As the air is removed from the cylinder, the penis is pulled further into the cylinder and towards the walls of the cylinder, the corposa cernosa, the sponge like material that fills with blood when a man gets and errection is expanded - making the penis larger.

Does pumping work? How long will the results last?

This depends on a number of factors. The length of your pumping session, the frequency of your pumping sessions, and the sizes you achieve with the pump on. It would be possible, with daily pumping to maintain the increases constantly if you have the time to pump that often. Your penis will stay quite large for at least several hours after pumping. Most men find that over a period of time, that increases could be made permanment. Many pumpers who have been at it for several monthes or years will cite increases of two inches or more. There are numerous pictures and document cases of people stretching lips, earlobes, necks, so it stands to reason that continuous vacuum pumping over a period of months or even years would result in a larger penis.

How much of a gain can you expect?

It'll vary for each individual. It is possible to gain several inches in both length and thickness. You will experience gains immediately - even the first time you use a pump. However to maintain them you would have to use the pump on a regular basis. Most men get much larger increases in girth(thickness) than in length. It's difficult to say 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. Again, the increases in girth will be much larger, and longer lasting. If you're more concerned about getting increases in length it is suggested that you not buy a cylinder which is too much larger than the width (though don't get it too small in diameter - you need some room) so that your penis will get more of a pull in length, in a long cylinder, than of pulling outward (girth). You may also wish to consider the Extender - which is a traction device specifically for increasing the length of the penis.

How do you get started?

While you may have noticed a number of penis pumps in adult bookstores, or in the backs of magazines, for someone who is serious about enlarging their penis through vacuum pumping, only higher quality, more expensive pumps will work properly. The principal is the same for all of the pumps, the difference being that most of the inexpensive ones are not able to achieve a high enough level of vacuum to really work well, whereas the more expensive ones have higher quality parts, form good seals with the body, and achieve high vacuum levels. The inexpensive cylinders also tend to be made so cheaply that when high levels of vacuum are achieved the cylinder actually starts to collapse, kind of as if you were to suck the air out of a two liter plastic bottle. Another thing that happens with them is the base of the cylinder will flare out, as you apply increasing levels of vacuum, eventually destroying the cylinder. You can get an excellent pump, which includes a cylinder, and a hand pump, for as low as $100.

General Advice on pumping :

To get a good seal some men shave the base of your penis and testicles back about an inch or more so that when they put the cylinder a good seal is easier to obtain - but this isn't required. If you do shave the day before you pump, because if you cut yourself while shaving and immediately apply the pump, any bleeding may be aggravated ( though usually not by much...) It helps to apply the pump with an errection, though it's not required. Some men actually use the pump to help obtain an errection, because it pulls blood into the penis - and helps to make it erect. The pumps do have medical uses for men who suffer from impotency. Pumps can be used to obtain an errection, maintaining it errect with a ring, removing the pump to engage in intercourse. Begin pumping up. You may wish to press the cylinder against your body to keep your testicles from being pulled up into the tube. This is painful for some men (though some men pump them as well, to really big sizes). The important thing to remember is to take it slow and gradual. Increasing the pressure too rapidly will cause bruising. Don't be overly worried about it though. Enjoy the experience. If you're healthy, any bruising usually goes away after a day or so. Never push to the point of pain. If it becomes at all painful, release some of the pressure. Pump it up until you're at the highest vacuum level you can comfortably obtain. Leave it on for a while, watch television, read a book, surf the internet... To obtain the best results from pumping you need to go for longer periods of time, an hour or more. If you have more time, go for more. Your increases will be larger. As your penis gets larger, increase the pressure some more, again, only to the point where you are still comfortable and not in any pain. Most men are amazed at the size increases which are possible. I read one faq which discussed creating your own pump out of PVC pipe. I wouldn't recomment this at all. If you can't see your penis, you're unable to monitor progress, or see if there is any discoloration. You need to be able to watch so that you can be alerted to the need to stop. Plus it can be quite pleasurable to see your penis double or more in girth, and gain an inch or two in length. It's well worth the cost to buy a professionally made pump and cylinder.

Is it dangerous?

When done carefully, it is perfectly safe. The most frequent problem is someone who is overly anxious to see their penis very large, and goes overboard on the pumping, applying too much pressure to the penis. Applying too much pressure can result in temporary discoloration of the penis, and water blisters. Most symptom usually disappear after a few days. The important thing to remember is to go slow and increase the vacuum gradually over a longer period of time, so that the change in size is not traumatic and does not cause damage to the penis. Long sessions are better than short high pressure ones. You will not harm yourself if you use low to moderate pressure. It's perfectly safe and pumps have been in use for many years now by thousands of men.

Warm Water Pumping

Never use an electric powered pump or toy anywhere near water. You risk electrocution and may be severely injured or die. Never use water with an electric pump. If you're using a hand pump many pumpers have reported that pumping while in the shower with warm or hot water can be very pleasurable. The warmth may also help the penis to expand. The brass hand pump sold by Newart will work either dry or with water. Give it a try.
