Vacuum Pumping 101

Turns out my 2in diameter tube is too small for me. So I guess it’s to continue with my 2.25in pump. I have some silicone, it’s diameter is 0.7. I will try to use it and see if it’s too tight or if it’s okay. Thanks guys.

Where’s the best place to purchase those type of sleeves?

I got mine from Aliexpress. I just checked, turns out they have different sizes of sleeves.

Thank you for this thread. This helps a lot.

I don’t know how much hassle it is to import things to Nigeria, but if you buy a tube online and it doesn’t have a stated diameter, it’s most likely to be 2.25".

If you want to try a smaller size, you might try making a liner. Every now and then I come across high-density, closed-cell foam packing material, 3 or 4mm thick. You can cut something like that to put inside the tube and take up some of the space.

Back before commercially-made tubes were easily available, a lot of men made their own, gluing them up from plastic pipe or tubing. There are some examples in the archives if you want to give it a try.

It’s quite easy these days. I will just have to get another tube. Any advice on pumping for length?

Start at 3"Hg for 5 minutes. If you don’t have petechiae or a donut, add two or three minutes every day until you do, then back off until they go away. After a few weeks, start bumping the vacuum up .25 or .5"Hg at a time, until you get petechiae or donuts again. That’s the limit of what you can do in the tube.

Some men use high vacuum and shorter times, some use less vacuum and longer times, but most men use some variant of the above.

Thank you.

Has anyone used the CTC electric pump I am getting one soon and wondered if someone had used one of these and could give me a review of it.

If I use my pump to hang would that work?

Like put my member in the pump but don’t pump it up and just let it hang like a wieght?

There are several threads on this pump. Just enter CTC in the search function (upper right hand of your screen) and they’ll pop up for you to choose which ones look interesting to you.

Two items to consider: 1) amount of weight of a vac pump and cylinder, and 2) where the weight is applied.

A stand alone cylinder (vac pump separate from cylinder) does not weigh very much. The type which has the pump attached to the top of they cylinder does of course, have more weight, but I am unsure how much it is, so can’t comment if the weight is enough for an adequate hanging routine. However:

A pump cylinder under vacuum attaches at the base of the cylinder and the pubic region surrounding the penis. In my opinion, very little of the weight will impact the penis, so no, I dont think it will work as a hanging option.

Might be stupid question but when you are about to pump do you feel horny and get erection that way or do you feel nothing special and just mechanically give yourself an erection without being horny? Is it mandatory to be actually horny with 110% rock solid erection for pumping to work properly?

Never did pumping hard. I always started it flaccid and slowly grew to its max. I find it interesting that people can get aroused while doing it as I never did.

I pump with both Bath mate (mornings) and vacuum (afternoons if I am working from home). My suggestion is to get used with it slowly and try it with different approaches (pressure, time, using lube, etc). I would not recommend pumping hard as it could blown one of your upper veins. Take it easy :) its a looooong journey.

I said this once before, but I often go into the pump flaccid or with a semi-hard erection and then the pump pressure fill things out and I get a full erection.

I did find however that once I am fully erect in the tube and at full pressure, it is kind of a "fake" erection. The dick is hard but it doesn’t know it (sort of). If I then start watching porn or some other stimulus that would get me an erection naturally, I can "FEEL" my "fake" erection kind of opening up and letting more blood in. I believe your body releases Nitric Oxide when you get an erection which relaxes the internal structures and lets more blood in so your penis engorges and become erect..

With the "fake" erection, it is hard, but I believe that the internal structures are still in a flaccid state. When I mentally feel the natural erection happen, as I said earlier, I can feel things open up and see my erection get bigger and fuller in the tube.

I often use this as a finishing move in the pump for the last cycle (5mins or so).
