Penis-measurers of the world, breathe easy: you have been validated. A new study, carried out by sexuality researchers at Indiana University, has found that the average erect penile size is exactly 14.15 cm (that's 5.57 inches). That number is notable not because it differs from previous studies, but just the opposite: it's quite in line with prior research, "suggesting that men likely self-report data accurately—or at least reliably—to research teams." (A choice excerpt: "Although many men may wish their penis were larger and may expend significant effort toward penile enlargement, this does not necessarily mean that men overreport their penile size to researchers.")
Carrying out a scientifically accurate study on erect penile size is
hard difficult, it turns out, because most men have a strange tendency not to develop a full erection while being coldly observed by scientists wielding measuring sticks. Strange. Which is why studies such as this one must rely on men to self-report their sizes, which can also, err, arouse suspicion about the accuracy of this study, for obvious reasons: how do we know these penis stats confirm prior penis stats if these penis stats also rely on self-reported penises? It's a penis paradox!
