I think if you had the time and insane level of dedication you could gain 2-3 inches in length and up to 2” in girth.
The amount of continued effort that would require would mean you wouldn’t have much of a life outside of pe. You’d literally be pulling and tugging and clamping and hanging and stretching and stroking and bending the thing 10 hours a day every day and even then you’d be waiting 3 or 4 years before you got to where you wanted to be and who knows just how useable you’re dick would be at that point?
If at all..
I’ve gained an inch with minimal effort but my genetics helped in that department however I think everyone, absolutely everyone can gain an inch from pe with a bit of application and willpower. Let that be your base and anything above that be considered a bonus and you’ll be a happy man. Anything else could almost be considered delusional and potentially dangerous.
