I don't know...all I know now is that I saw a few members said something like "I got praise from my 7+ inches.", "my own 7 inches was considered big enough.", "partners I've been with all said my 7 inches is big enough!"...and so on, but they didn't have any photos in their album! Even the OP didn't provide any pic to prove he got 7 inches!
What a interesting coincidence!
But I did see a similar thread in my country, the original OP posted his dick around 17 cm (6.64 inches), which was taken with a ruler attached and a paper showing his ID, he challenged other members to do the same to compare! So far, about 25000 people have seen that thread, but only like 40 people have the guts to post, let alone just a few had bigger dick than the OP's! Compared to a thread asking what's the measurement of the members there by clicking the provided numbers(it went in this way: What's your measurement? 5 inches, 6 inches, 7 inches...) in that forum, most of the them "claimed" they had 5+ inches! Even the average fell in nearly 7 inches! If people there were all being honest, why there were like only ten 7+ inches cocks appearing in that former thread?
But I know there might have some factors stopping people from posting what they've gotten, first of all, they chickened! They didn't have the bravery to expose their privacy, which was totally normal reaction, 'cause not every one is exhibitionist! Some people just don't want to show their monster no matter how stunning it could be considered, second, I think only people have the "should-be-prond" tool are willing to show off! In other words, only people who are self-conscious about how well-endowed he has gotten, have the guts to show. A guy who knows he doesn't get a bigger, thinker weapon won't show his "less-endowed" for not being laughing at in the first place! Last but the most important thing, THIS IS A INTERNET AREA! With the anonymous factor which Internet has provided, people could "claim" whatever they want behind the computers! It's not that you could sue them for bragging, or you'll make all the efforts to find out who's behind the screen for exposing the big liar's identity. Hey! Forget about the Internet! Even with two bros being completely naked in a locker room, they'll lie about the true measurement when the size conversion comes. Unless you see it, and measure it with the right method, there is really hard to decide what's the average, or if 7 inches is considered big or not.
Just some shallow, stupid thoughts...hope I didn't offend anyone!
