Eh, obviously plenty of people disagree with that sentiment, as noted by the posts above. It's not insecurity, it's just generally being annoyed with the atmosphere of bullshit and fantasy on all the site. Like has been noted - none of the big boys seem to able to prove it. Nobody is mad, just pointing out how lame it really is.
And so far as the size thing? I'd say 6" and 8" probably make a difference for sex, and girth and length usually split pretty evenly in female preference, but girth usually has a small advantage. Either way, I thought we were all supposed to just be Penis Enlargementing for ourselves and our own body images?
It seems like there really are two kinds of posters here now: one group who says "it's stupid to care if anybody is making shit up, who cares, it's a support group, it's fun to fantasize, just worry about yourself," and the rest who say "this is ridiculous, it sucks that people are so dishonest, it makes the site look like a joke."
Facts are facts, none of the 'big boys' on
MOS seem to able to back up their claims. Like I said, if it were any other kind of forum, people would call bullshit left and right. But the fantasy is a big thing around here, so those who embrace it get defensive when people call attention to it.
