Does this prove my penis can be longer?
Lying on my back with an erection, I use my right hand to hold it flat against my abdomen. I put my left hand, palm down, across my abdomen with the knuckle of my pinkie (smallest) finger touching the tip of my penis. Leaving my left hand in place, and not moving in any other way, I use my right hand (OK grip) to pull my penis up, and its tip comes a centimeter or more closer to my navel.
Does this prove that I have potential for* length gains? Why/not?
Stated less absolutely, is it valid to say that this provides evidence that I have potential for length gains?
*further in my case; though I'm thinking of newbies
