Selecting Your Cylinder Size

◀ 1 212223242526272829 109 ▶

hey i had a question about cylinder size and i did not want to make a new topic so i will ask it in here. im not sure if i got my math correct but if you get a 2” tube and you fill it up will your girth be about 6.2 inches? also if you use a cylinder size that is just a little bit bigger than your unit in girth will your dick eventually fill up the pump? when i say eventually i mean after a few months or a year.

Started May 2010- 5.9 BPEL X 5.5 MSEG

January 18, 2011- 7.0 inches/17.7cm BPEL X 5.5 MSEG

Goals- 8.0nbp X some more base girth

I’ve frankly never understood the whole “sizing” concept and ensuing arguments for penis cylinders.

Per Pascal, fluid at rest is isotropic, meaning it acts with equal magnitude in all directions. Air easily qualifies as a fluid. Therefore, equal pressure (or vacuum) is seen at all points of the penis as long as all points are exposed to the pressure (vacuum) level of the cylinder. For a dick that’s 6x5, It wouldn’t matter if the cylinder is 6.25x5.25 or 9x7. The pressure (vacuum) will be distributed the same.

Groovetube,

True but the base might not create a good seal with a cylinder that is too large and your testicles could get sucked in the tube more easily.

What, you’re saying that’s not comfortable or something? :( But really, the pump industry would rather sell us multiple cylinders at $80 a crack than provide adapters (sleeves or open-ended acrylic lids) for much less bread. They have us thinking all wrong, keeping this debate alive, just to boost profits.

The pump industry likes to sell cylinders on the small side, so it won’t take long before the customer comes back to order the next size up.

That is why I made my sizing chart that is based on buying a tube with room to grow and comfortable at the same time, so you get maximum usage from your purchase.

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.

Yes, your girth would be on the order of 6.28”. Then you would buy the next cylinder size up and eventually fill that cylinder making your girth 7.0”.

Gprent,

Are you saying if your girth fills up a 2” tube, you should go up to the next size? I mean I use a 10x2 Homemade tube and my girth can get up to 6”. I’m not sure if I want more girth can that right now. But I notice my length gets up to 7.3 BP. How long you think I can continue to use this? I pump 6 days for at least 1 hour. My focus was length, but wife really likes the girth.

Now: 7.1bpel/7.25bpfsl/5.4meg

Goal: 7.5-8bpel/6meg My stripper name will be HUGE HEFNER

I was just answering passwurds question. No, you don’t have to go to the next size up if you are happy with your girth in the 2” tube. Besides, you can still get up to 6.25” girth in the 2” tube you are using, so no need to upgrade, especially if the wife is happy.

Now what about Length? Am I doing whats right to really increase my length?

Hey gprent, I have a quick question;

I want to get into pumping. I will be going for length. I found a tube on ebay that is 9” X 2”. I’m currently 8” BPEL. Will this cylinder work for length work? Thanks!

Well, it gives you 1” to grow lengthwise and that should be OK, but the main factor in selecting a cylinder is the diameter compared to your girth so you get the best fit. What is your erect girth near the base?

Yes, stick with that tube, you can’t get a better fit.

I’m about 5.75” MSEG, not really sure of the base, I know it’s not much bigger than that if any. Thanks again for your help.

Yes, that 9”x2” will be perfect. Buy it before someone else does.

I’m on it now lol. Thanks, gprent!
