Penis pumping - affects on a curved penis?

Question: Does penis pumping change the curvature of a penis?

The reason I am asking this is an odd one - I would like to keep my natural curvature that is not due to Peyronie’s disease.

Does anyone know, or have any experience with how a pump affects this over time? As I assume that what I have is genetic and not due to scar tissue I assume it will not decrease no matter how much I pump?

It has the perfect up curve, not too severe and not too subtle either and I’d love to keep this during my PE.

My curve that I did want to lessen was not impacted by pumping. I saw your other post discussing cylinder size. You do need to understand how your curved dick will fit in a cylinder. It can be very uncomfortable if your glans is pressed into the side of the cylinder due to your curve, and in some cases bruising may occur. A larger size cylinder may be needed to fit comfortably.

Ah yes I did think of that and my novelty pump which is 7 inches girth does result in my glans touching the side but not strained. I was thinking a 2 inch tube won’t be so bad and will prevent my testicles getting sucked in?

I also made a 5.25 inch girth pump from some filter parts I had lying around and it doesn’t seem to hurt but will keep a close eye on it.

Shame there isn’t such a thing as a curved pump!

My other concern with having a pump that’s too big was something I read on pressure being too much if theres too much space in the tube? - which is also why I’d love one closer to size

My curve isn’t severe but it’s a nice one I’d like to keep so thanks for the reply on that topic.

If your glans is touching in a 2.25” tube it definitely will be in a 2”. Keeping the glans well lubricated will reduce friction and allow it to slide up the tube.

To keep your testicles free, stretch out your sack a little to get your balls a little further away, then place your cylinder tightly against your body and hold it in place until your vac level has been reached. Keep stretching sack as necessary if you feel “testicle creep” during your session.

I am unsure what you mean by a 5.25” girth pump. At the tube sizes used for PE any vac pump will work for all. The volume difference is so small that a mechanical pump will not exceed its design capability. In fact the vac levels we use are so low that a mechanical pump is not truly needed. Some guys just use their mouth to suck the hose and create a sufficient vac level. A mechanical pump is more convenient to use, and an electric one is more convenient than a hand pumped one. An electric pump allows you to overlook minor leaks in the pump/hose/cylinder arrangement.

Just clarifying terminology here: vacuum is the absence of pressure. When you increase the vacuum level you are reducing pressure.

I also do not fully understand your last point about too big a pump resulting in too much pressure if the tube is too large. If your vac level reads is -5inHg on the gauge, it does not matter what size tube is used or how much space is around your dick. Tube size decisions are made when your penis is touching the sides of the tube and the penis is not exposed to the full vac level.

Examples:
A penis with a “baseball bat” structure (glans larger than base) is plugging up the tube and the base is not getting the full vac level. You need a larger tube.

Your penis quickly enlarges and the full shaft is “packing” the tube with only the glans and a small amount of the shaft being exposed to the tube. You probably need a larger tube, although you could be only focussing on the glans.

I have an upward curve that I like and I can’t imagine getting in any cylindrical pump without my glans pressing against glass. I think with proper lube its fine. I usually feel more pressure at the base to be honest.

Thank you for the reply.

Sorry, what I meant by the ‘5.25’ girth is that I made a makeshift cylinder out of a filter housing I had lying around and it has a slightly smaller diameter than the 1.75 tube (1.67). I used this to test how much my shaft packs the cylinder and to see if my curve is an issue, which it doesn’t seem to be. It goes up the tube no problem with minimal lube, if any and stays there throughout the whole pumping. It might be because I put it in semi-erect but it doesn’t hurt either way or seem to bruise as I keep the pressure low and at 4hg/inch max.

Oh. It was just something I read elsewhere on other websites but I could have quite easily misread it so please ignore the part about the tube being too large.

From what I understand so far I believe the 1.75 and 2 may be beneficial with alternate use as I have yet to pack the 1.67 diameter filter tube I have been testing with. I have about 75% at least still to touch the sides during a session. In fact I would continue to use the makeshift cylinder I have if it didn’t have such a narrow entrance that digs too much into my skin after a 10 minute session and leaves a distinct mark which would result in bruising if I used it too often.

Anyway, thanks for the replies and I think I have a better idea now what I will need.

I’m not sure what you mean by “beneficial with alternate use”.

If you are not packing a tube, it does not matter if you have 1/8” gap between your dick and the cylinder or 1”. A gap is a gap and the vac level impacting the penis is the same.

Some guys find a benefit of a two stage (two cylinders) system. If they are packing or close to packing one cylinder they will use it for a session then switch to the larger cylinder for a short session. The thought is that when packing or close to packing the first cylinder you are working on length and by switching to the larger cylinder you can get a little girth focus.

I have been pumping for 10 years and my upward curve has not changed.

Ah right, I bought the two cylinders as it was cheaper that way anyway and I will move up to the 2 over time. For now I will stick with the 1.75 until I am able to pack it fully.

Thanks for all your input.

That’s great news!

Your current girth is what I am aiming for.

I reduced my curve to the left by about 50% in the first three years but I included a lot of effort going against the grain with jelqs also. My curve was from an injury. So I’m happy about it. But my girl said she loves the way the curve feels So I’m not working on it anymore.

Thank you for your input. Good to hear it works for injuries, though that sounds like it was largely due to all the effort you put in with the jelqing.
