Selecting Your Cylinder Size

Thanks

Either. There is no disadvantage to a longer cylinder, apart from the fact it is harder to get in the sink to clean, and it makes your penis look slightly smaller :)


Heat makes the difference between gaining quickly or slowly for some guys, or between gaining slowly instead of not at all for others. And the ideal penis size is 7.6" BPEL x 5.6" Mid Girth.

When selecting length, choose a cylinder that is between 2 and 3 inches longer then your bone pressed erect length.

For selecting diameter, use the table below.

<table class=”tborder” cellpadding=”4” cellspacing=”1” border=”0” align=”center” width=”50%” style=”text-align: center”><tr><td class=”tcat”><strong>Base Girth</strong></td><td class=”tcat”><strong>Cylinder Diameter</strong></td></tr><tr><td class=”alt1”>3.50 to 4.50*</td><td class=”alt1”>1.50</td></tr><tr><td class=”alt2”>4.75 to 5.25*</td><td class=”alt2”>1.75</td></tr><tr><td class=”alt1”>5.50 to 6.00*</td><td class=”alt1”>2.00</td></tr><tr><td class=”alt2”>6.25 to 6.75*</td><td class=”alt2”>2.25</td></tr><tr><td class=”alt1”>7.00 to 7.50*</td><td class=”alt1”>2.50</td></tr><tr><td class=”alt2”>7.75 to 8.25*</td><td class=”alt2”>2.75</td></tr></table>

*If you are at the upper limit and are going for length, select the cylinder diameter straight across in the table. If you are at the upper limit and are going for girth, select the next cylinder size up. Example: Your base girth measures 5.25. If your goal is length, select the 1.75 cylinder. If your goal is girth, select the 2.0 cylinder.

Hello Gprent,
my base girth is 6.30 inches. Girth in the middle is 6 inches. My goal is the length, is okay to take a cylinder 9x2.25?

Thanks

Yes, that is the correct cylinder for you.


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.

You gotta ask titleist lol


BPEL: 8.35"/ NBPEL:7.0" /EG: Apprx. 5.5"

Thats why i suggest a cyllinder of no more that 2” greater thsn your erect length.

Part of pumping is feeling bigger.

Hi, I take that these recommendations are for air pumping. So, if I were between 5.5 and 6 I should choose a 2” cylinder. But what if I wanted to use the cylinder for water pumping should I aim for a bigger cylinder and what kind of a bigger cylinder should I take into account?

Any advice?

All of my water pumping experience has been done with large 4” cylinders or sun tea jars (STJ) with a 4” opening and involve full package pumping, cock and balls. There used to be an on line video pumping site and everyone that water pumped on that site used these large cylinders to do full package water pumping. One reason for the large cylinder is that the large volume of water involved holds the temperature of the warm water for a much longer time then a smaller cylinder would.

Here is the LongJohnny 4” cylinder that I use for full package water pumping: https://www.pumptoys.com/prod/longjohn.php

And here is how I do full package water pumping in an STJ: Full Package STJ Pumping Pics

Now most hand pumps and certainly all electric pumps and not designed to have water sucked into them, so you also need a larger cylinder that can accommodate the water and still leave enough room for an air pocket at the top of the cylinder so that when you pump, you are only sucking air out of the top of the cylinder and not any water. It is a little tricky and takes practice to get it right.

Thanks gprent,
the cylinder 9x2,25 is perfect for my cock!

Regarding cylinder size and the chart on the first page of this thread, is it relevant in choosing size to the elliptical thick wall cylinders available from vacutech? I currently use a 2X9 flared cylinder which is adequately sized for my penis base at 5.5” however it cones out towards the tip down to 4.75 and therefore becomes rather cumbersome to pack the tube.

I have gained a bit due to consistent pumping recently at the tip and am now at 5” however I get annoyed with the doughnut and therefore am considering the smaller 1.75X9 cylinder. Would that be the best way to go for me to work on both length and girth? Otherwise I was considering those elliptical units due to their contoured shape and advertising that they aide in both length and girth.

Please do advise as I would highly appreciate the insight. Thanks lots

Our sizing chart is based on round cylinders. I don’t have any experience with an elliptical cylinder, but for the price, you sure don’t want to get one too small. For sure, you do not want to buy a round 1.75” cylinder because you won’t fit into it and packing is way over rated. To focus on length, go for longer continuous time in the tube and I would suggest 30 minutes without a break at a pressure no higher then 5”hg.

I would suggest comparing the circumference of your round cylinder to that of any elliptical that you are considering.

Your 2” cylinder has a circumference of πD or 3.1416X2= about 6.3”

Now, use this calculator to figure the circumference of the ellipticals that you are looking at:

I am 6.2, and your chart says I would need 2.25 for length or 2.50 for girth, but with the veins, my penis is already about 2.25 wide. Would it create much problem if I went for 2.75 or 3 inches wide tubes?


10/05/14 >> 7.7x5.8 (start stats on 10/05/14) / Short term goal : 8x6 (achieved on 14/06/14 and 23/04/14 respectively)

Mid term goal : 8.5x6.5

Long term goal : 9x7

The problem with using a cylinder that is too large is your balls getting sucked into the tube and since there is not enough room for them, it is uncomfortable to painful. Perhaps with a 3” there would be enough room to accommodate your balls, but if you really want to do full package pumping, you would want a cylinder even larger then that, all the way up to 4”
