I’m going to get some and try it.

So your tubes are thinner than your erect girth and force you to expand in the length direction.

Yes. The pull is remarkable.

I have gained my lost length from a long layoff and gained and extra 1/8” since I started this thread.


Began December 2009 at 5 7/8" length and 5" girth.

As of December 5th 2012 7 3/8" BPEL and 6 1/8" base girth.

Going for the magic 8"x6"

The tube I’m talking about has an inner diameter about two inches across, and my erect girth doesn’t fill it.

So this would work girth primarily?

There is also a tube about 1.5 inches across that I can’t enter while erect. So if I enter flaccid, then pump, it will work length more?

I believe so. That’s what I’ve been doing.

It would be so much simpler if they’d just sell clear pvc. I also went with a nylon barbed fitting because the brass one broke the cap. Can’t wait to try this thing out. Any advice on water pumping without the gauge?

Your only option is to go by feel.

The wider tube will allow girth expansion.

What I gave found using the narrower tube is that my girth has lessened somewhat, while the length is longer.

Interesting. I wonder if gaining girth would maybe cause a loss of length also. That’s probably why getting the right cylinder size is so important. The right size probably allows you to maximize both length and girth. At least I imagine so.

Your cock must be greased well before going in the tube. At any time during the pump sesssion are u achieving an erect penis at the smaller girth while in the tube?

When you come out the tube you have post pump length gains which are noticeable and you said also mysteriously slightly larger girth?

I have a 6.2” erect girth so a 1.75” cyllinder should do the same thing for me.

I use olive oil.

I measured morning wood a week or so ago and it was 7 1/2”, a 1/8” gain from my last maximum measurement.

I also lost girth, not gained.

I don’t think we can imagine anything in PE, we have to do the work and see what happens.

My feeling is a that one can’t do both length and girth, because they warrant different tube diameters.

Id lose girth for an additional 1/2” length. So its kinda like dough it can be stretched in different directions, you only have so much.to work with.

a-unit just read this. I made my pump many years ago similar to yours many years ago, but mine was all clear. I bought almost all my parts from McMASTER-CARR. Go to this page and click on the ‘TUBES’
picture, not the ‘TUBING’ picture. http://www.mcmaster.com/#polycarbonate/=vft0w8. I also bought a small sheet to cut a circle of the outside diameter of the tube and glued it on with Lexan adhesive that you can get at any local hardware store. It has to be Lexan adhesive since it act like pvc glue. That will give you an airtight seal, but do not make a mistake when gluing these parts because there is very little chance allowed to correct something if needed.

I bought aquarium air tubing valves here http://www.amazon.com/Jardin-Contro…uarium+air+pump. After I suck the air out, I shut it off. As you will see, It is all inexpensive.

What do you think?

Would you then say that for girth a tube that is at most BPEL(or even smaller)might make sense?

While at work it occurred to me that a large medical syringe might make an excellent tube. Something in the 300 to 400 cc variety. They sell them on Amazon for about 12 bucks or so.

I think that’s what is happening.
