Selecting Your Cylinder Size

I have noticed that I can’t go fully erect in the cylinder. This is strange because I’m only 5,2” wide and the cylinder are 1,75 * (3,14) = 5,49” - 5,2 = 0,29” free space. Still you have to count with those walls who probably is about 0,3 - 0,4” wide. Therefor I think I’m too big (5.2) for the 1.75 if my calculations are correct.

What kind of lubrication do you use and do you put it on your entire cock?

I’m not good at lubing my cock. That may be the problem. Anyway, is it dangerous when you cock is forced to the cylinder wall and you start too pump and expand your cock girth, building up a huge pressure on the sides? Can’t you rupture something?

First off, you have to become good at lubing your entire cock. Once you try it, it will probably solve all of your problems. When your entire shaft from base to just below the head comes in contact with the cylinder wall, that is called packing the cylinder. How can you build up huge pressure on the sides when you maintain a constant vacuum force? Hopefully in the 3”hg to 5”hg range. Keep your pressure in the normal safe range and you won’t even come close to rupturing anything.

Great thread.

I am 4.8” at the base and am going for the length. Should I get the 1.50” or 1.75” tube?

You are really just a little too big for the 1.5. Buy the 1.75.

Thanks gprent.

My BPEL is 5.7”; should I go with a 8” long tube over a 9” one?

Yes, an 8” length should work nice for you.

Thanks gprent; placed the order.

TodaMoon, you’re exactly my size!!! Please, let me keep in touch with you just to know how things are going with you. I’ve bought a pump too, and a cylinder exactly the same size as yours (as gprent recommended), and I hope to start pumping as soon as possible!

All the best for you!

P.S.: One more things… guys, would someone like me or even TodaMoon (just mentioning him because we’re the same size, and starting at the same time) take any advantage of the use of two different cylinders? I mean, two different sized cylinders? I bought the 1.75 x 8, and I am running for both lenght and girth! Any suggestion?

Ok Gui, my brother from a different mother.

Let’s pump this up.

I ordered a pump a few days ago and I’m waiting for it to arrive. Unfortunately I didn’t find this thread until today. My stats are 6”x4.5” and ordered the 8”x1.5” tube, I am aiming for both length and girth. I think from what I have read here that the tube I have selected should be alright to start with, based on your experience and knowledge, would it have been more beneficial for me to go for the 9” tube rather than the 8”? Also, I didn’t order the lube when I ordered the pump, what lube do you use? KY Jelly alright?

Thanks

So should there be one tube for length and one for girth?

The cylinder you selected will fit OK. I am pretty sure that in the not so distant future you will will be thinking about ordering a 1.75” diameter tube. When that day comes, you can buy a 9”X1.75”.

I use a generic brand of KY. When you use water based lubes, just have a bowl of warm water handy so you can use it to refresh the KY as it dries out. You won’t have to add more lube, just add a little bit of water to keep things going.

No, not necessarily. The first cylinder you buy should be selected to fit as best as possible.
