Late thanks to SDP!
All of the gallery pictures are you, right? I don't have the privileges to see anything but thumbnails, but there's a pretty wide range of shapes and sizes between them, as well as the self-suck xtube videos and stuff. Either way, that's as close as I've seen anyone get to a proper measurement picture after they pass a certain size.
We saw in that 'can anyone show 8 inches' (
http://www.lpsg.com/46547-ruler-pics-can-anyone-show-42.html ) thread, even on this site showing just 8" is rare. 9" is extremely rare and over 10" is unheard of. Again, I'm talking about this site in particular, a site dedicated to big dicks.
As I said, I sort of came to the conclusion a while back that once guys pass a certain "real life" measurable size threshold, your chances of them being honest with others about their
true size, or complying with the known measurement rules, begins to
rapidly diminish. I'd put that line somewhere around true 8, but I guess it could be lower depending on the person. From observation, with the select few that truly exceed 8.5 or so, you've almost lost any chance of them
not exaggerating by some margin, and the only real question ends up "How much do you figure this
particular guy is lying by?".
Of course the blame for all of this still probably lies with the originators: all the John Holmes crap, pop media,etc. I think when someone sees a dick the same size as their own (or smaller) in porn, and realizes that the ignorant majority out there believe this guy to be 12 inches or more in length, they may as well claim something close for anything that 'looks' similar. Chances are good that way more people will believe it than won't.
