When people talk about pumping here, they speak about “high pressure”, increasing pressure, etc. But when you pump, you’re actually reducing external pressure, not increasing it. And the pressure inside your penis is actually staying the same. If you look at your gauge it actually probably puts a minus in front of the numbers. It’s just really confusing because the gauges seem to be calibrated around the STP or NTP air pressure (about 1 atmosphere) and not around 0, which creates the absurd illusion of negative pressure and then this negative pressure gets confused for an increase of pressure.

So to summarize, when we create a vacuum, we reduce pressure which makes our penises expand because the internal pressure stays the same. Increasing pressure would be the equivalent of wearing a tight condom, or releasing the valve to return to normal pressure (Which brings the question, how much pressure condoms do on our dicks? We could pump with a condom on until we reach normal size and the gauge would tell us the pressure the condom is torturing our big dicks with, but that is for another thread.)


10/05/14 >> 7.7x5.8 (start stats on 10/05/14) / Short term goal : 8x6 (achieved on 14/06/14 and 23/04/14 respectively)

Mid term goal : 8.5x6.5

Long term goal : 9x7

Yes, there is confusion in the terminology of pumping. I try to use the phrase “increase or decrease vacuum” but even then there is confusion. A simple example of your point is: assume a flaccid penis is in a cylinder without leaks; pump the cylinder to a vacuum of 5” Hg and do not pump any more; the penis will expand in size; the vacuum in the cylinder (measured by the gauge) will decrease to less than 5” Hg.

There are lots of discussions here about the use of condoms and silicone sleeves to apply positive pressure to the outside of the penis while pumping. The goal is to reduce edema in the skin while expanding internal tissue structures.

It is a high negative pressure or increasing negative pressure. You might as well get used to it, because that is the way all the worlds pumpers talk. High vacuum pressure means less air then normal atmospheric.


The primary goal of PE should be to make your penis as healthy as possible in both form and function. If you do that, increased size will follow.

“use of condoms and silicone sleeves to apply positive pressure to the outside of the penis while pumping”

That sounds absolutely counter-productive. Wouldn’t that act exactly like a smaller vacuum?

I have never pumped that way and personally would not recommend it.

The challenge with condom or silicone sleeve pumping is discovering the proper amount of vacuum to overcome the tension of the sleeve without injury to the glans or meatus. The latest trial is using a “glans protector” with powder. There are other threads here that discuss this approach in detail.

How about using a silicone sleeve whilst pumping with the bathmate?

Starting on 2013-08-16 :EL: 5.75" (14.6cm) / EG: 4.75"

From my understanding our bodies are under pressure all the time due to the atmosphere. This is why we have an internal pressure that is an equalizing pressure or opposing force, so that we don’t implode from the atmospheric pressure. This is why when we are cut the blood and other liquids come out because it is under pressure and our skin and other underlying structures, veins, arteries, organs etc., are designed to hold those fluids in under various pressures.

What happens when we pump is we create a vacuum like in space. We remove (to a degree) the outside or atmospheric pressure inside the tube and this causes the internal pressures of the body to push outward unimpeded. This is why we get Lymphatic fluids built up in the tissues because our bodies are pushing that fluid outward all the time. It is only the opposing atmospheric pressure that keeps it all in balance and where it belongs within our bodies.

So the effect of pumping is actually from the inside out and not, as it would seem, from the outside pulling outward.

If that makes sense.


Current 5.5 NBPEL x 5.75 Base EG - 5.25 MSEG 7" BPSFL

Short Term Goal 6 NBPEL x 6 MPEG

Long Term Goal 8 NBPEL x 7 MPEG (why not dream BIG?)

Who is that retarded, I mean really .to not understand that when you put your cock in a cylinder designed to seal at the base and suck out air decreases atmospheric pressure, 14.7psi at sea level

So it’s an relative vac level , if you pump to 4 on a mountain be careful at sea level

So it is confirmed, living on a mountain is like perpetual pumping. Anybody wants to go to the mount Everest to test it?

Mid term goal : 8.5x6.5

Long term goal : 9x7

A lot of people, I would wager, do not understand the effects of atmospheric pressure on the body and what it means to remove said pressure. So I explained it the best I could in terms that I think anyone could understand.

Slow down on the retarded use.

Obviously this thread is attracting the science folks!

What you see on the dial is something called gauge pressure. It’s basically measuring the pressure differential - the difference between the absolute pressures in the pressure vessel and the outside atmosphere. It typically is subtracting the absolute ambient pressure from the internal absolute pressure inside the pressure vessel, but in this case, the higher pressure is on the outside. I would guess that the pressure differential you feel pushing outwards when you pump is VERY close to the reading on the gauge, but slightly (negligibly) less.
