Um... no. See, not just baseball's biggest cock, but the WORLD's largest documented cock, is 13.5", so... just, no.
And as usual...you cite a long ago (one study over with only a few hundred participants over 50 years ago) as the end all truth...how did you get to be a "moderator"? You are nearly the epitome of the things wrong with LPSG...Large Penis SUPPORT Group....not from silly folks who automatically discount what they have not seen but "can't be true" mentality.
Thousands join LPSG...then disappear...and never stay and pay for a membership...why should they....they are challenged or they see "challenges" and called liars to anyone who posts what they know to be true...
Why should any new member stay and join if they share anything that a few folks on LPSG...a moderator among them...always jumps in and calls them liars?
The world is a far bigger place than a small group of LPSG members have chosen to believe it is and attack and denigrate any thing they themselves have not seen.
