Packing may contribute to girth gains.
I have also adressed this in the condom pumping thread but didn’t get a response, so I will try my luck with a new thread. Condom pumping seems to give very good expansion post pumping, and this may also be beneficial for girth gains. It seems that the condom actually increases pressure inside the penis, as the penis is unable to expand as much when a condom is used. When the condom is removed the penis compensates by expanding more.
Some of the pumping gainers (eg. Peforeal) have reported that the best gains have come at the base, which is also the part that is usually packing the tube. I am wondering if the packing is causing high pressures by prohibiting girth expansion of the penis, much like condom pumping does. Of course the penis is still able to expand in length, but this may not be enough eliminate the effects of the prohibited girth expansion. If this is the case it might be the reason why many pumpers experience their best gains at the base, where packing mostly occurs.
Furthermore it might explain the overall phenomenal gains that Peforeal has made (he is my hero hehe). His sessions have consisted of pumping until packing and then moving a cylinder size up. When the packing is stopped the post pumping expansion occurs, due to the mechanisms mentioned above. As the pumping continues with a larger cylinder this expansion is enhanced and may contribute to increased girth gains.
What do you guys think? :)
