Question:

I just got my pump back, Lost my other one (story I don’t want to get into). I was pumping a while back and want to incorporate it back into my Routine but have a quick question. Here it is.

I have a 4 6/8 girth but a big mushroom head. When pumping before in the 1.75 cylinder, the head would explode huge and hit the walls. My question is this, When that happens, is that trapping the air below the head from coming up above? Or when the shaft expands will it push the air up above the head? I am planning to do Advocets routine if anyone is curious. Thank you for your time. =)

We can’t answer that with any certainty. However, I have a wide glans also which gets squooshed up against the sidewalls of the tube in what looks like a pretty tight seal, yet there is plenty of vacuum pressure for the shaft below.

I borrow this thread. Can I get a straighter penis if I start to pump? Now I have a n-curve but I want a straighter penis.

Gone60 I can not add anymore than what Avocet8 has stated as he is better versed with those matters and seems to have a unit more aligned to yours. Klonkan, if you do a search you may find some more information regarding this. I for one have quite a curve to the left, like a banana however I am of the mind that pumping can and has at times corrected this in some measure.However to fully make a conclusion such as that I would have to do very isolated pumping and conduct a proper test. Thus there is not sufficient conclusive information to say that pumping will for sure correct this as it depends on a variety of matters however if anything pumping has a great probability to correcting to some degree.I hope I have managed to answer your question and one more thing Klonkan, start off with the Newbie routine first and then ease into pumping once done and read Avocet’s pumping bible titled Vacuum pumping 101. Good luck and best wishes.

I have always wondered the same thing. I notice an enormous difference in my glands and shaft when using the 2” tube over the 1.75”. I know that the tube circumference has alot to do with that, but I know that my glands are being limited because they look as if they are being smashed in the smaller tube. Also, with the air being trapped, I wonder if that is limiting girth expansion in the shaft. If anyone has any other comments, I am sure the original poster and myself would like to hear from you.

I seem to remember someone came up with at least a band-aid solution for this problem. It involved placing a soda straw or similar small tube on the inside of the cylinder that would act as a pressure transfer tube.

Yeah I have an upward curve, and the top of my glans usually gets smashed into the side as well and the edge of my glans turns blueish after awhile.

OT abit but just wondering if using mineral oil based lotion for lubrication is alright for pumping ?

Miburo:

It’s poor form to ask the same question in multiple threads. My answer to you when you asked that in Need help please was "Mineral oil may not be a problem with the cylinder, but may be a problem with the pump seals."

Sorry about that. I’m not sure about this but does lapdist’s pump have issue with the seals against mineral oil ? Thinking of getting that.

You shouldn’t let any liquid get sucked into the internal workings of a pump with a gauge. The mineral oil should not hurt the cylinder, but keep it away from the quick disconnect O-ring seal.

Oh you mean from the top of the cylinder ? I see.. I was just thinking do I really need a lubricant in the first place and even if I do use the oil it will be at the base of the penis only.

Btw how does lapdist’s package come in ? I mean I don’t wish let my other half knows so it is in a discreet package ? I emailed lapdist but their email support is really weak.
