Water pumping

123

I think having a hard erection is essential. I don’t believe the vacuum expands the tunica. I think that what it does do is take external pressure off so that internal pressure can have a greater effect. In other words, hardness and constant kegelling are critical factors in making gains with a pump.

IMHO

A vacuum pump will induce an erection by definition. This is its actual porpoise and it does it really well. The point is it gives you a passive erection, which means that the circulation of blood is less active than when you have a real one, in fact, afterwards, some have to wear a cock ring in order to prevent it to subside. Certainly, being able to have a real erection while pumping would help, but refraining from pumping just because you don’t have one would not; indeed, most people would not have an erected state for one or two hours a day (unless they are copulating like rabbits), it follows that they have to accept the fact that most of the training time is passed in a state of passive erection, which is still better than not to train.

Sorry to harp on this, but the above is incorrect. The expansion of the tunica depends on the pressure difference between the inside of the penis and the surrounding medium, and it does not matter if that medium is air or water. If your gauge says, say, 5”Hg, then the pressure differences is the same for air and water. Compressibility does not matter. Trust me on this.

However, the expansion may also depend on the temperature (as it makes the tunica more flexible), and, as we agree, water pumping makes for easier heating.

hmmm, maybe you’re right, but I’m not sure we’re talking about the same thing.

it was said that if you pump in water you feel strain at a lower gauge read.

I’m not arguing that pressure is not the same thing in water and air, I’m just saying that the situation is more complex than two chambers with different pressure. You have three: outside tube, inside tube and inside penis, where the gauge read is the sum of the penis and the tube pressure.

By adding a incompressible medium in the tube you eliminate that complexity, now you’re just left with the tension force from the stretched penis. My point is that the only force acting on the gauge now is just the tension forces from the stretched fibers inside the penis, and not a sum of those and the negative pressure in the tube. That’s why I think it’s right to say that you can feel a greater stretch at lower gauge reads with water pumping.

As you stretch fibers in cc’s and cs, they act like rubber-bands, exerting forces to counter the expansion. These forces also shows up on the gauge.

I’ve tried to make a little sketch to show what I mean.

Ft= is the force from the penis fibers.
Fa= is the force from the air with low pressure, suction force.
Fp= is the force exerted by the pump.
G=is supposed to by a gauge.

This is how it looks in my head; the decompressed air is acting as a rubberband between the penis and the force from the pump. This is causing higher readings than with incompressible water. On the other hand, the water is acting like a string.

I don’t think I’m far off here, but please correct me if I’m wrong

And my opinion is that a passive erection is just a weak erection. If you’re not producing pressure from the inside, then you’re not stressing the tunica, hence no gains. IMO :-)

Where’s the two hours come from? I don’t pump for two hours.

Either you stress it from in or outside, your tunica will receive some sort of pressure: negative or positive. I had tunica gains by pumping: believe me. It takes long time at low pressure. Indeed, why should everybody take for granted it takes two hours a day to hang and not to pump, anyways. Better it is to stress it from both sides, hence the convenience of jelqing after pumping and I would add, from pumping after hanging, to top it out with clamping after jelqing.

I know it takes a lot of time…

1 - seat on a bidet and fill it with warm water, put the cylinder and the tube in the water to get warm.

2 - use a creamy soap and literally wash penis and balls creating a good foam.

3 - apply as usual the cylinder and start creating a regular air vacuum by sucking the air with mouth.

!! Watch your balls or they’ll get sucked in, which most people don’t like !!

4 - once a medium pressure is achieved bend the plastic tube to prevent the air from going back in the cylinder and put it in the warm water

5 - release it and the vacuum pressure will start to absorb the water in the cylinder.

6 - suck again, trying to suck the air and not the water and do it again and again until only water is in the cylinder

7 - create a reasonable pressure, seal the tube by bending it and wrapping the bend with a little elastic and start your session.

This way of pumping gives several advantages:

1 - warmth helps tissue expansion
2 - water, being a more dense fluid than air, distributes the pressure more evenly and comfortably
3 - bruises, fluid buildups and donut effects are greatly reduced
4 - Girth increases much more with long sessions at low pressure in warm water.

I hope it help someone


I don’t understand how to get water into the cylinder. Do you have a pic ?


21/03/06: BPFSL 7, BPEL 7.2 , EG 5 GOALS: BPFSL 9x6.5 or death

Current: 6.5 NBPEL Goals: May 30: 7.2 NBPEL

My Progress and Routine

Keep the plastic tube under water, and the negative pressure will suck the water backwards into the cylinder, repeat over again.

Taped onto the dashboard of a car at a junkyard, I once found the following: "Good judgement comes from experience. Experience comes from bad judgement." The car was crashed.

Primary goal: To have an EQ above average (i.e. streetsmart, compassionate about life and happy) Secondary goal: to make an anagram of my signature denoting how I feel about my gains

I read the step by step instructions. Okay…my GED is just not kicking in. Is there a video that someone can recommend?


BPEL Start: 5 15/16". BPEL Current: 7 1/4". Short Term BPEL Goal: 7 1/2". Long Term BPEL 8"

BEELIT Start: 6", BPELIT Current: 6.1/4"

EG Start: 5". EG Current: 5 1/8". Short Term EG Goal: 5.25". Long Term EG: 6

A passive erection does not stimulate grown for most if us. I used to only pump, with a raging erection, and had some growth. Now I’m doing stretches and squeezes and by the time I get to BM I’m too tired to get a strong erection. I’m not getting near as much results from the bathmate, just edema.
