Guys, I am not sure about what you state here. Especially tripod, I am convinced that with the right technique and amount of time and heat and dedication it is, even for a quite thin penis, possible to pack a 3 Inch tube. I know that not many pumpers can do so, but in my opinion it only lacks dedication and time invested into that goal.
I am pretty sure that most pumpers could pack a 3 incher if they just tried Long enough. I can take weeks and months of hard work to pack the 3 incher, but I am pretty sure that it will be possible. We will see.
Nothing is impossible.
The limitations of growth will fall to the usual culprits:
1). The penis is surrounded by fascial tissue sheath that is primarily made of collagen (similar to ligaments and tendons). This sheath is a BITCH to enlarge and requires
time to expand. My fascial sheath doesn't want to budge until at least 15 minutes of pumping for example.
2). The skin of the penis isn't normal skin... it's glans is laced with delicate capillaries which the penis needs to replenish it's blood supply. The skin of the glans penis is just like the skin of your lips. Those capillaries can easily become damaged with too much pressure too fast or too much pressure over time.
3). The friction and subsequent compression from the vacuum pressure (and from the tube when packing) can damage those delicate capillaries. Those delicate capillaries are
essential to getting good erections. The same friction can also cause contusions to the glans of the penis. This is when the capillaries have been damaged and the surrounding skin is filled with the hemorrhaging blood and lymph fluid.
4). And I don't have to really mention blisters...
Having the diabetes type-2 gene (or type 1 for that matter) can cause a slowdown in capillary healing and also make them more vulnerable to damage. There are lots of other health problems that can interfere with the health and healing ability of the delicate capillaries of the glans of the penis.
Uncircumcised guys have an advantage that they can pull the foreskin over the glans during pumping... the area that needs to be protected is the area right below the ridge of the penis head. In circumcised men, this area takes the most pressure and compression.
Flat out... the skin has limitations before it fucking splits.
Pumping up to 8.5" girth from a natural 5.5" girth leaves me vulnerable to capillary and skin damage. But... I NEVER get to regularly pump and so the start and stop effect always fucks me running.
The key to achieving 9 or 10 inch girths would be regular pumping. Not pumping on and off like I do... regular pumping
without damaging the capillaries and skin of the glans will lead to bigger and better results over time... it's the damage that can set us back because while you are healing... you are not able to pump and not being able to pump means that all of the previous gains will slowly wither away during the healing process. This can create a negative feedback loop where the pumper is locked into a cycle of damaging the glans and skin due to infrequent pumping (because of the damage to the skin and glans) and will eventually have to stop for a long while so the penis can heal itself.
Good luck and just... be ever so careful okay?
