Inner Tube Pumping

Solution for the Glans?

I am not clear on why the glans needs a solution?

“Solution”—not in reference to any liquid to apply to the glans, or anything like that. Rather, solving this problem:

If you condom pump, then the whole penis is covered and vacuum pressure is distributed evenly. To be more exact, whatever portion of the penis & glans that aren’t “stuffing” the tube are still exposed to more vacuum pressure than the portion that is pressing against the walls of the tube. But if everything is covered by a condom, then pressure on the exposed (“un-stuffed”) areas is evenly distributed, lymph is not drawn out as readily just beneath the glans, and hence a donut is avoided. At least that’s my understanding of it; I’ve only tried condom pumping once. Too much of a hassle and too expensive for me to try and jelq between three sets of pumping.

If you use an inner tube, and the end is open, then the end of the glans is exposed to quite a bit more pressure than the rest of the shaft and whatever portion of the glans that is covered by the inner tube. Some of us have tried gluing or clamping the open end of the inner tube, but unsuccessfully. Or wrapping Saranwrap over the glans… that didn’t work for me, either. As noted before, maybe the increased pressure (10” Hg) to adequately pump the penis up inside the inner tube needs to be backed down to something less strenuous on the tip of the glans.

In my case, the increased pressure on the glans has created a hard lump right between the meatus and frenulum. The lump doesn’t hurt, and subsides after a few hours. Whether that’s a matter of concern or not, I’m not sure. But some guys report getting red spots, blisters, etc. on the exposed portion of the glans. For those wanting to pump with an inner tube instead of a condom, this is the problem that needs a solution.

Hope that clarifies. Again, I’m interested in comparing notes with you further regarding your inner tube pumpi

Yes it clarifies things. Thank you very much.

Here are the pictures of my condom and inertube experiments. Pumping Experiments

I tried three things pumping with a condom, with a short section of inertube over the problem area and a full sheath of inertube. I took pictures after pumping with a condom for 15 min and then short section a day latter. The condom was not nearly as good at keeping the doughnut under control but was much better did produce long term flaccid gains described by others.

I did the long sheath for about 2 hours with breaks and it was a big problem because the area on the underside was too short and caused a balloon like bulge that I didn’t see until I got out of the tube and I had to cut the inertube off. However the long lasting flaccid gains were very impressive. The little bulge like doughnut on the bottom was gone in hours the flaccid increase is still apparent 4 days latter.

Conclusions
If preventing the doughnut effect is your main Goal the short section of inertube over the problem area was by far the most effective. It can be placed more precisely and shaped to fit around the head and is far easier to remove.

If long term flaccid gains is the priority then condom pumping or the long sheath of inertube (be sure the rubber reaches the tip of the glans).

As far as a solution for the head I am going to try pumping with a condom over a short section of inertube. I also had the idea of your own custom fit latex sheath. I have made latex molds before. They aren’t cheep but should be reusable if you get just the right mats.

I am going to try pumping with the inertube sheath extending all the way to the tip of the glans first though. This should mean only the very tip is exposed to limp fluid build up. Which I never minded really anyway.

I started fooling around with inner tubes when I first got a pump, mostly to help get a better seal and to keep the edge of the tube from digging in. I started experimenting with longer pieces of tube to isolate the head. I got an idea that I am sure others have tried. At the end of a session with a long inner tube section that ended just below the head, I slipped the other end off the opening to the tube, and BAM-instant traction device. I have been reading through this forum. There is a TON of information, some of it is a little technical for me, but my understanding is that some kind of wrap after your done with your workout to keep your unit in traction is a good thing. I left it on for about fifteen minutes before the tip started getting a little cool, so I took it off. I am thinking about trying to extend this period. Has anyone had any similar experience? Any advice is greatly appreciated.

Gents,

If I try a cut piece of bike inner tube, what is the right size? Obviously, a racing bike tube (they are not too flexible anyway) is too small, but how about a mountain bike tube (I’m between 5.25” and 5.5” midshaft girth)? Or something in-between?

Or maybe I should ask on my next rip to get my bike tuned — “Yo dude, do you think this tube would fit over my dick?”

Moorth,

Based on your results, do you feel the long inner tube sheath is the best option? How much of a pressure increase were you able to use than you would normally? Lastly, after a good pump, is cutting the tube the only way you can get it off or is it possible to roll off?

The problem I ran into was the shape of the glans. It is high on the underside and the area that forms the doughnut was exposed and I didn’t realize this. As long as every bit of the shaft is covered, so that it doesn’t ballon out, the inertube should just peal off. Hold the end of the inertube that is covering the cylinder tight to be sure it stays in place will make it easier.

Thanks, Moorth. My problem is that I have a flared tube and I don’t see how I can spread the rubber sheath over its outside edge. It will have to go straight on the old tally.

Anyone else have suggestions on the right size bike tube?

Moorth—

EXCELLENT threads, both this and your pic one. I haven’t tried the short section of inner tube as a “donut guard,” but I have tried longer pieces of inner tube (like your photo, <dickininertube.JPG>). The one like yours that I’ve used comes up just short of the corona of the glans. The problem with that is that the vacuum pressure sucks some of the shaft (sulcus) skin out, creating pinching and/or donuting. Your picture illustrates avoiding that by just covering the dorsal side of the corona.

I agree that the advantage of an inner tube (vs. a condom) is being able to custom trim it to fit the shaft and/or glans as desired, but I haven’t experimented with “shaping” the inner tube—just using different lengths.

BACK TO “PROTECTING THE GLANS”…
The inner tube I’m currently using goes about an inch beyond the glans. I find that massaging the tip of the glans between pump reps (and after a pumping session) helps reduce any edema I get on the tip of the glans. But it would be nice to avoid any edema or lymphatic swellling altogether. I don’t want to mess with a combination of inner tube and condoms—that just adds time to my routine, and it’s too expensive. I’m wondering if there might be a cheaper/easier solution, such as the end of a large latex balloon. It could be cleaned and reused—rather than buying a bunch of condoms for multiple sets of pumping.
Anyway, I’ll be watching for your experimentation with a latex mold.

I never tried it, but sounds like a great idea. And since there’s lube inside the inner tube already, it shouldn’t be too difficult to slip off later on. The only problem is that my pump tube is flared and it isn’t easy to slip the inner tube off of it while my cock’s still inside it.

My EG started at 5.25; now it’s about 5.5. I bought the largest inner tube I could find at the time, it has a 2.125” diameter. In the pump tube, the innertube (and my cock) expand beyond that. It obviously doesn’t allow as much girth expansion as a condom would, but I’m satisfied with it for now; my cock is still very “plumped” after using my current inner tube. I’m on the lookout, though, for a wider innertube, like the ones used for old-fashioned “balloon tires.”

Avocet (big guy that he is) says his girth won’t fit bicycle inner tubes, but one can always “graduate” to a larger pump tube with a motorcycle inner tube to line it :) .

In my opinion, I like having an inner tube that extends beyond my glans. Without any inner tube, I was following avocet’s suggestion of pumping at 5”Hg. With a ten inch inner tube, I can very comfortably go up to about 8 or 9”Hg. Much beyond that and I get more edema on the tip of the glans.
I don’t have to “cut” any tube after pumping (why cut anything?). In fact, the inner tube stays inside the pump tube and I just “pull out.” Assuming I continue to gain girth, it may start inverting and “rolling off” my cock as I pull out.
When I made my set up, I flared the edge of the acquarium tube, and I can still turn the inner tube inside out over the tube opening. In fact, the flare may be what keeps the inner tube in place as I pull out. Just put the inner tube in place before you get lube all over your fingers!

Josh,

Thanks, that’s really great info.

I just bought a tube from the bike shop. The box lists its diameter as fitting tires 1.5” to 2.125.” I did see a size of 1.75” to 2.25” so I’ll give that a try if this one is too tight.

I have an 2” wide LA Pump tube. It’s got a pretty wide flared edge so I’m skeptical that I will be able to stetch the tube over it. We’ll see.

I’m back doing double condom pumping. I even tried a third condom the other night and packed the tube at the end of the 3rd set 10 minute. I can up the pressure to 10 hg quite comfortably with 3 condoms. I get some fluid build up in the turkey neck area under the glans, not too bad, but if I can further reduce it with the tighter inner tube while increasing the cavernosa expansion, then that would be ideal!

Well, I tried my new purchase. There was no way it would fit over either me or my pump tube. I guess it is back to the bike store….

I have been using the full length of inner tube for pumping now and I am really pleased with the results. The main benefit is you can keep going as long as you want and the doughnut doesn’t eventually make it impossible to get back into the tube. I think it also allows more effect on the CC and because the flaccid gains are impressive and long lasting. I haven’t experienced any problems with my glans.

Though I haven’t tried it, I agree you can probably pump longer using an inner tube… it just feels a lot more comfortable. The biggest roadblock I have is still having some swelling (edema) on the tip of my glans, esp. around the raphe. I’ve tried to cut back on the vacuum pressure a bit, but hate having to do that.

I see from your stats that your EG is 5.75. What amount of pressure (inches Hg) are you using? Do you jelq in the tube, and—if so—what amount of pressure do you increase to?

Your not going to like my answers. I suck until it gets uncomfortable then I let air in until it’s not. I don’t have a pressure gauge. I could have avoided mistakes early on if I had one I suppose. I kegel when I think about it but usually I am busy reading. Kegel is what you meant right? Or can you actually jelq in a tube?
