bigtiny454,
You can no more “cement” PE gains than you can “cement” a suntan, a callous or an 18-inch biceps measurement. Forget such a notion.
I’m sorry, but the responses in this thread are nothing but baseless speculations - mixed with pseudoscience.
I gained more length than you have, and I’ve lost nearly all of it. Same with girth.
I doubled the size of my erect penis, by volume, via rigorous PE. After having stopped PE, and retained all but 1/8” EL x 1/8” EG of my size - AFTER 3+ YEARS - I thought I was “living proof” of *cemented gains.*
Then the bottom fell out. In the ensuing months I kept losing and losing.
I suffered no illness, injuries, STDs, etc. I could find no alternative explanation as to why this happened…other than “cellular recycling.”
The GvM model (Growth via Mitosis) cannot provide any reasonable explanation as to how the onset of “decompensation” could have been so delayed (3+ yrs) or why my losses actually accelerated (once they began).
I’ve been through this song & dance here, ad nauseum.
PE gains are NOT permanent. However, a “maintenance program” is possible (in my deformation model) - it just isn’t as scaled down as one might hope for.
Good news: PE gains are real. As I said, in my case, I doubled the size of my woody.
