Has anybody ever heard of pump stretching?

Has anybody ever heard of stretching with a pump?

My friend says he has come up with a way to stretch the penis with a pump. I was wondering if he really come up with this Idea or if he could have read it somewhere.

OK this is his idea or not I do not know because he says he made up some stuff and I have found the same kind of ideas or stuff on the Net but I can not find anything on this idea. The only thing I found is pump hanging and he says that is not what he is talking about.

OK her we go. You have a long cylinder or tube with a piston in it that rises up the cylinder or tube whenever you create a vacuum in the cylinder or tube. Now there is a string or something like a string hooked to the piston and clamps or fastens to the head of the penis and when you create a vacuum in the cylinder or tube the piston rises up the cylinder or tube pulling on the penis. Supposedly you can have whatever amount of pull you want to have on your penis by how much vacuum pressure you have in the cylinder or tube. So you can very easily adjust how much pull is on your penis at any given time by how much vacuum pressure you create in the cylinder or tube.

Has anybody ever heard of this, and do you think it might be a good Idea?

Haven’t heard of it, but it sounds like the piston just increases the vacuum in the tube, which makes it no different than a standard vacuum pump (which uses a piston internally, incidentally). I.e., you’d be increasing the vacuum all around the penis, not just stretching its length. Unless you are packing the tube, but again, this is the same as using a pump. IMO. The closest practical product is a vacuum hanger.

No it create a vacuum and makes the piston rise up the cylinder. The piston has a string or something that attaches to the penis and pulls up on the penis and and stretches the penis when the piston rises up the cylinder. No vacuum is created on the penis. The vacuum is just between the top of the cylinder and where the piston.

Could you diagram it? It’s still not making much sense to me.

OK here is a diagram.
Ok you see where the vacuum is created between the top of the cylinder and the piston.

You see the piston with string or something that attaches to penis.

Ok what it does is when you create a vacuum in the tube between the piston and the top of the cylinder the piston will rise up the cylinder pulling up on the penis stretching it upward.

Wouldn’t tying a piece of string to your cock be a little dangerous? As the pressure increases inside the tube, I would think that the string would just start to dig into your shaft to the point of discomfort.

I’ve not heard of it, but it seems like a pretty good idea for a new device if it doesn’t already exist.

I’m technical and fully understand your concept; the idea is technically a hanger, of which, there are many versions. However— there is a big problem as I perceive: that a string around the glans will cut off circulation of the penis. Thus, it will turn bruise, darken, turn gangrenous and fall off. Keep those strings off your dick!!! The bib hanger and others spreads of the gripping pattern to allow for circulation. The gripping problems is the MAIN thing that inventors are investigating. Keep on thinking—Steve

Why not just pull on the tube you already are using? Wouldn’t that give you the same stretch factor? I have tried this before when I have fully packed the tube and you can feel a good stretch, but I don’t know exactly how safe it is to do it this way. The gauge can fluctuate 1-2 Hg while doing the pull.

If you could make a suitable and safe device to attach around the penis, I don’t see why it wouldn’t work. The next important question would be how much vacuum pressure is required to get a good stretch. For most men, going above 5 or 6 hg for any length of time is not good. I suspect that you’d need more vacuum pressure than this to get a good stretch. For this reason, I suspect that good old-fashioned hanging and vacuum hanging are better options.

As you can see I said not the string but clamps or fastens go on the head.
