Construction

The toy you need for all pumping action is the actual pump. I have gotten a very basic one made out of plastic which does the job and is light-weight. One of my more pumping experienced testees actually prefers this kind of pumps for traveling because they are light and simple so are quite sturdy. It has only two moving parts: The grip you pull for pumping and a button for releasing the vacuum located right next to the hose. The hose is 50cm long and made out of transparent silicone with a one connector at the other end which fits into the vacuum valve on the cylinders.

Cylinders are the toys which are put on the body part which should be pumped. All cylinders from LA Pump are handcrafted from a sturdy polymer. The most common cylinders are the ones for pumping your penis and I have gotten two of them. First there is the round thick-wall cylinder which gets his name from the 7mm thick walls. It is rounded at the bottom for a good and comfortable vacuum seal. The other cylinder is an elliptical one so its shape is more like the one of a penis. At the bottom is has a flange which is between 12mm and 17mm wide. The flange distributes the vacuum pressure more evenly making it more comfortable to wear over long time and more intense scenes. To determine the correct size for your cock cylinder a rule of thumb is taking one third of your dick’s circumference as the diameter.

Switching to the body’s rear I have gotten a rosebud cylinder for ass pumping. It is a 165mm long round cylinder with diameter of 75mm which ends in a rounded, elliptical flange which width increases from 11mm to 17mm. In the middle of the cylinder there is 254mm long and 25mm thick rod which is screwed and glues to the cylinder’s top. This rod goes inside your anus. Sadly this cylinder comes in one size only. So if your ass quiet experienced there can be a problem because the rod is too thin to form a vacuum along the sphincter. If that happens, don’t try to forcefully create a vacuum but continue pumping. This can lead to internal injuries!

For going up the torso I have gotten two nipple cylinders. They are 104.5mm long including the vacuum valve and have 7mm flange at the bottom for more comfortable long term scenes. To really feel the vacuum sensation on the nipple the internal diameter should be slightly smaller than areola.

Playing with the Pump & Cylinders

Getting ready for pumping takes a bit of preparation. The body area onto which the cylinder’s rim sits should be mostly hairless because hair below the rim can prevent a vacuum seal from forming. For a smoother experience some people cover the rim and the bottom 5cm of the cylinder’s inside or the soon to be pumped body area with lube so the skin can get sucked in more easily. Personally I did not feel the need to do so but if you are having a pinching sensation around the cylinder when pumping give it a try.

When you are ready to pump, connect the pump to the cylinder and lightly press the cylinder against your body so the rim sinks into the tissue a bit. Especially with the rosebud cylinder you might need a second person for this because regardless if you are in doggy position or lying on your back, holding the cylinder in place and pumping at the same time is a bit awkward and clumsy.  Slowly start pumping until you feel a bit of a draft sensation. Stop until the sensation slowly fades away, than pump again. The aim of pumping is to maintain a pleasurable pulling sensation all the time. Pumping too quickly can lead to injuries. Good pumps have a gauge so you can see how much suction there is already inside the cylinder. If you want to take a break while pumping and walk around with your cylinder stuck to your body or pump on a different cylinder, push the little leaver on the vacuum vavle and pull the hose connector out. The vacuum will be maintained. To release the vacuum, connect the pump with the cylinder again and push the button next to the hose. When cock pumping I personally prefer the thick-wall cylinder. Due to its thicker wall it is heavier and feeling the heavy, solid cylinder in my hand while I see my dick grow is a horny mindfuck.

After playing wash the cylinder wish warm soap water and if you use it on multiple partners sanitize it. The agents on the sanitizers can make the polymer dull so be prepared that over time the cylinders will lose a bit of their crystal appeal. Before using the cylinders again they should really be dry including the vacuum valve! Otherwise moisture can get sucked into the pump causing damage in the long run.

So much for the technical part; now to the anatomical. Cock pumps can have a beneficial effect on your sexual health and stamina. Pumping draws blood into the pumped body area increasing the blood flow making getting and maintaining an erecting more easily. Besides blood tissue fluid is getting pumped into the body area giving a puffy feel and increase the temporarily increase the size. When jerking off after pumping it will feel a bit like stroking a stranger’s dick which can be a hot experience on its own. Furthermore the light draft stress of the vacuum makes the nerve endings more sensible which lead to more intense orgasms or more intense nipple or ass play.

The Basic Trigger Pump without a Gauge

Cock pumps are often advertised to facilitate penis growth but sadly there isn’t scientific evidence that even after long and regular pumping your penis will permanently grow significantly. There can be a bit of increase in length and girth but don’t expect the increase to be measurable in centimeters – at least if you are interested in a rock hard dick. If you pump very often and for very extended periods of time the size will increase but the dick will feel soft and soggy because you are basically outstretching the skin and facilitate permanent tissue fluid accumulations. In a worst case scenario your dick will lose its ability to become hard. This “sponge dick” appears when you pump too quickly so the blood shooting into the cavernous bodies damages them. In a really bad case a blood vessel in your erect penis can erupt which is a case to call the ambulance! Pumping “hard” on body areas without cavernous bodies like the ass or nipple is not dangerous but can “just” lead to hematomas.
