I've had various guys & playmates comment on how "huge" I am and they can't believe that I'm only 7.5... Of course, this is likely because the other guys they've played with exaggerated their own size, or because they've taken the "measurements" from porn a little too seriously...

I think another factor is that a given size cock often looks bigger when its on another guy. A while back, a quite well endowed guy started playing with me at a sex club, complimented me on my cock, and I complimented him on his. From his comments, he was sure I was bigger, yet when I looked at him, he seemed huge, and I was sure HE was bigger.
Part of this may be that you see the other guys cock from a different angle and perspective than your own. But I also suspect that some of this is mental. For most males, being competitive is part of their nature, whether it be how well they play sports, who can buy the bigger toys, who has more nuclear missiles, or how heavy their cock hangs. When what you have is clearly superior, there is no need to second guess. But, when it's close, there may be a little insecurity, and this leads to overestimating what the other guy has. (Consider the US-Soviet arms race.) And, if the other guy clearly has more, and you have admiration, awe, or envy for what he has, you are likely to overestimate the difference.
