Vac based hanger pull and grasp

Based on Big Girtha explanation :

Simple analogy for compression hanger would be OK grip pull, When you pull, you stretch the skin + internals . That’s why excess skin is needed on back of attachment point.
For Vac based like Penimaser Pro, its like pulling your glans with 2 fingers, just internal penis is stretched. Here excess skin doesn’t matter.

Vacuum hanging confusion

How would you explain Vac based hanger like LG pull mechanism? Since we have part of shaft inside chamber.

I am at 3lbs with LG and feel like sleeves create a seal and grabs the whole penis with no blood circulation cut off.
Also the skin is not pushed forward like compression based hangers to form shoulders, instead a seal is formed. That’s why foreskin growth is minimal .
So we are not just pushing/stretching the skin down but kinda bonded with it using vacuum.

Maybe experienced hangers can explain better. The thread is 14 years old and designs have changed.
This would help in wrapping technique too.

Just got a reply from Dr Ric. He replied very vaguely . My email to him was asking design and wrapping.
”
So I take it that your uncircumcised, this is best using the LG H. Please take a look at the photographs attached. This creates a vacuum plus a slight compression attachment mechanism, thus such a combination works quite well with the foreskin pullover method.

The LG hanger is much more robust than the vac extender, not only gripping the glands but the part of the shaft behind the glands for more comprehensive attachment. “

I did quick 2 experiments:

1) leave excess foreskin in front
Here when you pull ,the chamber/attach weights the glans is pulled out a little , very little extra foreskin stretch as glans is not pulled much.
I am assuming a vacuum is formed in glans and area near it, This wont pull foreskin . Foreskin growth may occur due to vacuum and edema, That’s inevitable.
Seal because of sleeves so kinda whole penis pulled.

2) leave excess foreskin to base
Here when you pull , the glans is pulled more and foreskin moves to front creating more foreskin stretch.
More vacuum may help here but not worth it.

When I leave excess skin to base the seal is not tight and when I attach weight the glans gets pulled out.
When I leave excess skin to front the seal is tight and comfortable to hang 5lbs+ with no pump. Trying to understand this behavior. Mailed him asking this.
