A fucking flaccid cock longer than any proven erect cock in history. This thread is too much.
You will never change people's fallacies (phallacies?) It's the goose that lays the golden egg. Part of my job is being able to judge sizes based on sight and comparison and I still am not 100% accurate, who can be? I would be willing to bet that a great many individuals who claim the double digit fantasy is real wouldn't be able to accurately judge a prosthetic, i.e. you give them an 8" dildo and tell them it's 10" and they would believe it.
That's not to say that it absolutely does not exist. I don't deal in absolutes ever. I just think there is no way that anyone has seen them in the frequency with which it appears. Unless every single person who purports to have seen one has seen the exact same individual.
I have seen some very large penises and 1 (singular) massive penis. Like "holy shit is that real" massive. And I know for a fact, that it wasn't double digit length. Volume is another story, but that's not what is being quoted.
I suppose if people are counting the penile root, then sure, 10" is feasible, but visible length is something else.
