Hard to stay hard in the tube

Hey guys,

My problem is that if I go in the pump erect then after a few minutes my dick begins to shrink. It is like the vacuum can’t keep it erect, but the main problem is that eventually it will shrink more than semi erect. My glans won’t fill up that much, only the base.

I use really low vacuum, like 1,5-2 hg because over 2 I got pain. Today I tried to milk the tube and I could get harder and everything looked more efficient this way. If I don’t milk the tube nonstop, my penis starts to shrink again (beyond semi erect) and I get also little pain/discomfort at the base of my dick (I pump for 10mins every other day).

So my question: is it normal that I can only pump efficiently with nonstop milking the tube?

Also if I stay up I get more enlargement.

I also have some problem with my glans, for example in the morning it is cold and it will get warm after I walk a couple of minutes. My glans also won’t stay so full, maybe I have that f*cking venous leakage. It was always that way, so it’s nothing from injury or too much PE, that’s why I use low vacuum. Above 2-3 hg it is really too much for me, this sucks…

I am thinking to go to a doctor to check out my veins, but I hope that pumping will help if I do it wise enough.

So how about you, can you stay hard easily in the tube without milking?

Does pumping have any benefits if my penis starts to turtle?

I checked leaks on my pump but everything seems fine.

Thank you for all replies!

Leakage, yes, venous leakage…not so much.

Sounds like you aren’t getting a good seal on your tube when it’s attached.

What kind of equipment do you have (the pump, not the junk)?

I use Kaplan pump with a 1,75 inch cylinder. My dicks circumference is about 4,5 inch and about 1,57 inch wide at the base. I trim my hair and use baby oil gel, but I use only a thin layer on my cock and at the bottom of the tube.

If I push the tube on my semi erect cock and do 1-2 kegels while doing this, I already get a good vacuum but I also do 1 pump to make it sure.

I can pull the tube with quite a lot of force and it won’t come off.

Try a cock ring, get it nice and hard, then put it in.

I have the same thing, cannot get over 2 hg, wonder why that is?

Perhaps your problem is a bad seal.

Rather than using lube, or even a cock ring, have a look at this:

Sleeve Master

You can put this on and then fit the end of most tubes over it. You likely won’t need to use gel, oil or vaseline. Be advised that petroleum based products may cause the silicone to break down.

The other thing to check is the connection of the coupler on the tube. Sometimes these get loose and need to be tightened in order not to leak air.

Differential Diagnosis for Vacuum Leaks

Same problem here.

Even if I use 4-5 in Hg, after a few minutes my unit shrinks to a less-than-completely-erect size.

It’s not a vacuum leakage problem, the pump has a manometer and the pressure is quite stable.

Is it supposed to work like this or I should get a cock ring ?

I wouldn’t get a cock ring, that will likely make any sealing difficulties trickier.

So you feel that it is your own erection that is flagging once in the tube?

To a certain extent that is normal. You aren’t going to stay rock hard once in, but the pressure in the pump should make up for that. You shouldn’t be seriously wilting.

It goes more or less like ..
1) I get into the pump fully erected.
2) I get to 3 in Hg pressure, +0.5 inches length (I dunno about girth, but it increases quite visibly)
3) After 3-5 minutes, it shrinks back to fully erect size, but I can see and feel that it is not “hard”. It is soft, but big as it is when fully erected.
4) After 6-10 minutes, it is smaller than fully erect (just a little, I guess 0.25 inches, more or less).
5) As soon as I release the pressure, it totally shrinks down, I.e. It was the void pressure keeping the blood there, while my natural blood circulation wasn’t helping very much, if at all.

I see others have similar problems here.

My question: is it more efficient if I milk the tube all the time? With this method I can stay fully erect so I wonder does this make a difference?

Maybe others may try it too.

Try a vibrating massager (handheld back massager or something like it)on the tube while your in it. The vibration has helped me keep a solid erection with and without porn. You just have to be careful to keep it away from your head while your in the tube. I had the vibration on top of my glans one time and got a MASSIVE donut. Also, try to keep the tube heated with a rice sock or heat pad

If it is a problem with getting a good seal, Lampwick and PetitFaun gave me PERFECT advice on that here. Now it is perfect seal everytime:

Newbie can’t get a perfect seal — is continually pumping the pump ok?

Soft when I exit pump
