Selecting Your Cylinder Size

I see you recommend the length of the pump to be 1 - 2 inches longer than your BPEL, but a lot of manufacturers have set lengths like 9 or 10 inches and diameter is the only size you can choose. Will you still get the same result of it is 3 inches longer than BPEL?

Yes, you are right, there isn’t much of a selection concerning length, but 9 inches takes care of 90% of most guys. The length won’t affect your results.


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.

Thank you. Can you recommend a good / reliable site for purchase? I am based in the US if it matters.

It may be mental, but it’s harder for me to go for length in my 12” tube than my 9” inch tube. If it’s not a mental phenomenon and is actually a physical phenomenon, I don’t understand the mechanism.

It is very frustrating there are not many 10” or 11” (or ranges between) of tubes. I could use a 10” tube myself. The 9” is near its end I fear.

It probably is mental. In the 9" tube you can see how close you are to reaching the end and for me that gives me an incentive to get there. With a longer tube the goal of reaching the end seems pretty much unattainable, at least in the short term, and that can deflate your drive a bit.

Just keep using that 9" and when you reach the end have a party!

Anyone experience skin discolouration at base after several months of pumping? Base of pump packs almost immediately now and first 1.5” is lighter in colour.

Can it be that the rest of your cock has gone darker? That sounds more logic to me.

No. Rest of cock has remained same colour. Only base has gotten lighter.

While their products look good (products4men), take a look at this from their FAQs:

"Permanent gains of up to 5 inches in length & 3 inches in thickness…over a period of many months."

Do you find a thickwall more comfortable or one with a rimmed base?

I don’t have any thickwall cylinders.

I should be receiving a new Thickwall tomorrow.. They do ones with a rimmed base, but I’ve gone for another straight sided one without rim/flare at the base. The entrance of the cylinder is comfortably rounded. If you’re using very high levels of vacuum you will need to build up to them slowly, but your pubis gets used to the pressure on it. You can get a silicone donut base to fit the tube if you need it, which is very comfy, but I find it too tight around my shaft.

All injuries happen from "too much", or "too much, too soon" or "doing the exercise incorrectly".

Heat makes the difference between gaining quickly or slowly for some guys, or between gaining slowly instead of not at all for others. The ideal penis size is 7.6" BPEL x 5.6" Mid Girth. Basics.... firegoat roll How to use the Search button for best results

Had a question about tube size. So I started with a 2 1/4” which was edema city. Then I bought a 2” which works great for my first 2/3’s but then I end up with a massive doughnut. I then purchased a 1.75”.

My base girth is 5.75” but my unit tapers extremely at the end. Just over 5” from about 3/4” below the glans. I also wanted to try and get a good stretch.
I have tried coconut oil, olive oil and astrolube gel with a touch of water and I can’t get as much length in the tube as I can with my 2” it’s as if my skin sticks limiting movement down the tube.

Are there any other lubes I can try? I recently started wrapping where my doughnut forms and it’s been working great to help out glans girth. Still unable to pack the glans but basically pack the rest as soon as I’m in the tube. I would like to continue using the 1.75” until I can pack the glans but with it limiting length in the tube I feel it’s counter intuitive.

Any advice or help would be greatly appreciated.

PS the wrap actually glides smoother than my unit with coconut oil working best but still sticking vs sliding down the tube.

As always, this was very useful. I’m sharing it with some of my buddies too!


Do not have anything to do with godless myths and fables of old women. Instead, train yourself to be godly. Physical exercise is of limited value, but Godliness is very dear, a pledge of life, both there and here. This is a trustworthy saying that deserves complete acceptance.

It is very likely you do not have a cylinder problem. You have a problem with using too much pressure or pumping for too long or both. So, how much pressure are you using and how long do you stay in the tube?
