Pumping with cylinder that's too small

This is only a temporary situation, since I have ordered a 2.5 x 10 cylinder from LA Pumps which should be arriving within a week. At present, though, I’ve been pumping with a homemade 2” cylinder made from an aquarium gravel vacuum. I immediately pack the cylinder pretty tightly (my EG at base is 7.0 and at mid-shaft, 6.0). I’m pumping at 3” for 5 minutes, occasionally going up to 4” or 5” for a minute or so, several times a day. My goal has more to do with improving erectile quality and helping with ED than with going for size gains. My question for the vets is whether I’m likely to do any harm using this undersized cylinder. If so, obviously I’ll just quit and wait for the few days until the other cylinder arrives.

Thanks for any input.

Holy shit, 7” base girth! You must only be able to get about half of the length of your dick in that 2” tube; I’m 6” girth and need a lot of lube and patience to ease into my 2” tube. Even then it’s one almighty squeeze.

Yeah, irishjim. I can only get all the way in easily if I start flaccid. Semi-erect, like on a second set, I have to more or less stuff in as much as possible with my fingers. Totally erect, the tube “bottoms out” an inch or two from the base. No matter which way I start, once I apply vacuum, the fit is so tight that I was a little concerned about circulation problems, but my dick looks and feels OK afterwards. I think everything is probably fine, but I’m just so new at this that I guess I’m running scared. That’s why I was looking for a little reassurance.

I think you might as well wait. There is more potential for harm then good and it is clearly problematic to fool with.

Thanks, gprent. I definitely will wait.

I’m glad you replied. I’ve read a lot of your posts on the “Cylinder sizing” and “Pumping when you have ED” threads, and I was hoping for someone like you with a lot of experience to reply and give me some good advice.

Although I may not rank in with veteran status based on some forced experiences with my 1.75 ” cylinder I second what GPrent has to say. I mean in my experience it has not necessarily be detrimental in a manner which lead to notable damage or anything but its did nothing for me. I was packing that tube so much that it was not possible for me to expand any further.

I used a too-small tube for a while, It was impossible to get on with an erection. It didn’t cause me any injuries, but the benefits were not noticeable.

One of the goals of pumping when you have ED is to gradually increase arterial efficiency. You have a network of arteries just under your shaft skin - whether you can see them or not - which supply the CCs to expand the shaft. A tube that is too narrow only squashes these arteries rather than allowing them to open and expand. I agree that you’re better off waiting until the large tube arrives. Meantime, practice some jelking, which will help.

Do you use an ED drug during your PE sessions, or no?

Thanks for replying, avocet 8. I received the 2.5 inch tube about a week ago, and have only used it on three days, partly because of lack of privacy—lots of children and grandchildren present as houseguests during the holidays. Actually, it turns out that the 2.5 inch tube is a little too big. The 7-inch girth that I have at the base is only with a rip-roaring 100% erection, which I don’t always achieve. Otherwise, the tube tends to suck in a fair amount of scrotal skin, and occasionally even one ball. I don’t achieve a complete seal, and usually have to do some pumping throughout the whole 5 minutes to maintain a vacuum. I’ve been going for about 4 sets of 5 minutes at 3.5 to 4.0”, sometime going up to 5.0” because I know it’s going to quickly fall to a lower pressure anyway. I’ve gone ahead and ordered a 2.25 x 11 cylinder as well. It hasn’t arrived yet, but I suspect I will easily get a good seal with it and will eventually be using the 2.5 cylinder as a second stage.

As to the ED drug, yes and no. The first couple or times pumping, I didn’t use one, and I was working with about a 75-80% erection. Yesterday (Friday), I did some edging along with the pumping sessions and had pretty much 100%, though not necessarily long-lasting, erections because I had taken a Cialis on Wednesday morning and had had good sex on Thursday. I usually find that the Cialis effect lasts a day or so beyond the purported 36 hours. Then too, I can have pretty decent erections even with direct stimulation even without an ED drug, but they just depend on continued direct stimulation and are not long-lasting without it. I seem to go through cycles of pretty good nite wood alternating with cycles of sort of ho-hum erections (like right now) and I can’t really put my finger on what is making the difference.

I’m interested in ballooning, and I’m trying to stimulate the non-trigger areas, but at present they aren’t enough to maintain a good erection or get me close to ejaculation. The edging I’ve been doing is the more conventional edging using the trigger point areas.

And BTW, I am doing jelqing and stretching with a small number of horse 440’s, ulis, and Sadsak head exercises mixed in. And, of course, Kegels.

Since it sounds like the 2.5” cylinder is more than big enough, try pumping without using lube. This should eliminate the scrotal skin sucking problem. Just try to enter the tube with an erection and bone press the cylinder as you start and you should get a good result.

Good move. As you’ve discovered, there is a big difference between a 2” tube and a 2.5” tube.

I’ve eliminated the lube and also shaved some hair around the base where the cylinder makes contact. This has made a big improvement. I’m still not getting a perfect seal, but it’s much better. I’ll keep you posted. Thanks for the tip.

The 2.25” tube arrived today from lapdist. At last, a perfect fit. I can form a seal with no problem, and once pumped up the pressure stays constant. I did 4 sets of 5 minutes. It was easy, and I’m sure I can soon get up to the 6 sets suggested in the thread “Pumping when you have ED”.

The last few days I have been using the 2.5” cylinder without lube as you suggested, gprent, and with practice I got quite a bit better with it and I managed, but not nearly as easily as with the 2.25”. Soon, I’m sure I’ll try it as a second stage after a few sets with the 2.25”.

Wolfgang21:

Glad to hear that the 2.25” cylinder is working out for you. Let us know how things go.

I just wanted to add on here.

I have been pumping in a 2.25 inch cylinder. I have always been a wide, oval shape in thickness. Maybe the cylinder has been too big for too long.
Maybe I should try going back to a 2 inch and get a straight wall. I could probably fill it in a different way and CHANGE THE SHAPE of myself !

What a concept!
