Yeah, you're kind of right I guess. But about saying guys on this site aren't hung, even though sometimes it's partially true, I just want to bring up the fact that some of them (including you) are very lenient on themselves when measuring. For example, correct me if I'm wrong but it looks like you have your penis laying on a surface with a measuring tape on the side. This basically shows you measuring from the bottom/side of your penis, as opposed to the "official" way of the top. Also, you're giving yourself close of an inch of "head start" in that picture. I am barely 6 1/2" when measured from the top, but if I were to take a picture exactly like yours, it'd read that I'm easily over 7" (by the way, I'm aware that I'm not "big" and I did not join this site to make myself or others believe so).
Now by that I'm not saying you're a cheater nor that you don't have a big penis (you have a very large penis), I'm just saying that lots of guys (not just on here) do this, plus ontop of that round up. So basically, for example, a cock that's like 7 1/2" turns into, say, 8 1/2", which gets rounded up to 9". There's also trolls that just create accounts on here saying they're 10, 11, 12" but no pictures so it's safe to assume that 9/10 times it's all bullshit.
This also explains why dozens of scientific surveys prove that the average is something like 5 1/2", but every guy who is average claims he's 6". They measure from the side or top which gives them an extra half inch or more. Some go as far as rounding up like I said, which is why these same guys would say they're "about 7 inches" if you'd ask them in person, or if they feel so compelled to bullshit online.
About saying that other men seem to have small cocks, I think you're just very used to your own. What seems more logical, you have a "kinda big" cock and everyone else has small cocks, or you have a very big cock and everyone else has average cocks?
In my opinion, if anything, maybe I have a "kinda big" cock, even though that's an overstatement. I'm just a bit larger than average. Still within average range though. I guess if I were maybe 7 x 5.5, it would be "kinda big", withing the whole spectrum of sizes from tiny to humongous
