1) 31 cm is not 14" but 12": you have acknowledged this.

2) There is no credible evidence that there has ever been a penis 12" long.

3) None of the photos in your gallery show a penis that even appears to be of that length (though it follows from (2) that none of them could show such a thing).

4) It is obvious that none of the photos show a penis having anything near 9" of girth.

5) The photos do not appear to show the same penis.

6) The only possible conclusion is that you are a fucking fake. But, as there are as many credulous idiots out there as there are liars, I am sure that you will find some fools who will believe your fatuous pretenses.
