Flaccid penis size can fluctuate based on temperature, body posture (standing vs sitting), any stress you might be feeling at the time. Maybe Mandingo was a little nervous being interviewed in a talk show? I've never seen him in porn, so I wouldn't know what would be considered an appropriate or reasonable flaccid penis size based on his erect measurements.
The theory around anti-turtling and healing or recovering while being in your max flaccid condition has merit. I doubt Mandingo engages in any penis enlargement exercising, he is naturally gifted and doesn't need to get any bigger based on the measurements he has. He makes his money doing porn and could probably care less about his flaccid size. I've just never heard of anyone who has a 8" flaccid penis, but only is 6" erect.
I wasn't actually using Mandingo as a real argument; more of an anecdotal one.
I doubt Mandingo never did any form of P.E.. To be honest I've never looked into him specifically, even though many porn actors have clear signs of P.E. (besides those which grew clearly and considerably throughout their careers).
You may never heard of anyone with 8" flaccid but 6" erect, but I've sure heard of many 1" disparities favoring the flaccid and some, albeit very few and not much greater, even bigger.
The theory MIGHT have something to it, but the rationale behind it seems too simplistic and flawed. The claim that "healing elongated" would make you heal "at that size" would imply, for instance, that healing not elongated would also make you heal "at that size", which in turn would mean you wouldn't grow at all depending on your weather conditions. :snow:
Now... this is a radical view for we all know it isn't true but so far, this being the only logic forth exposed, even if the claim is not so radical the rationale must be incorrect. If the theory stands true, many variables sure are missing.
