inb4 ruler pics or proof, just giving an example, I've had girls think I was 10 inches many times. In reality, I hit 8 inches properly measured. See how that works? You take a large penis, and people assume it is much larger. SDP is bigger than me, and doesn't measure 10 inches, but I'm sure he could show an unmeasured picture to someone and claim 10.
There's that, camera angles, lense tricks, aspect ratio fuckery, etc...and a whole lot of "Give it up guys, t hey are real, I was at a nudebeach/bath house and I totally saw this guy, he was at least 11"! Go look around more!" for what will fill these threads as an "argument of proof".
We have threads on this forum with hundreds of pages dating back near a decade in search of a legitimate 10 incher. Guess what, not one has been shown!
Mandingo is generally considered the largest penis (Length wise) in porn, possibly in porn history. He is around 9.25 inches long. Doesn't that tell you something right there? In a business of big dicks and it's entire history that the biggest is not 10 inches, and that no one has come forward with legitimate 10 inches, that maybe, just maybe they don't exist? What next, 15 inchers just because we haven't seen one, might b e out there? Big foot might be, too.
