It could be nervousness. Or a chill. Or nonchalance. Or maybe just a fact of nature. What does it matter?
From the Los Angeles Times of July 4, 2011:
"Penis length cannot be determined how big his hands or feet are—those and other supposed indicators have been widely discredited for years. But now a team of Korean researchers has produced what may be a more reliable guide: the ratio of the length of his index finger to that of his ring finger. The lower the ratio, the longer the penis may be, the researchers wrote in Monday in the Asian Journal of Andrology."
That's a novel idea.
It started with 144 men aged 20 or older who were about to have urology surgery. The doctors weren't thinking about penis length then.
Except for two of them. Med students, I'll bet.
The first researcher came up with the idea of comparing the lengths of the index and ring fingers on the right hand of the guys about to have surgery. That provided a ratio.
The second waited until the patient was anesthetized. Then the researcher measured the penis length when flaccid. Next he (or she; the story doesn't say) gave a nice tug on each penis to see how far it stretched. The ratios were jotted down.
The two researchers then examined their results. Voilà! The ratios of finger length and penis length correlated nicely.
"Although it may seem like the results are coming out of left field, they actually are not," the Times reported. "A variety of studies suggest that the ratio of the two finger lengths is determined by prenatal exposure to sex hormones, both testosterone and estrogen. It is not unreasonable to assume that penis length might also be."
This study also has a moral for men: Don't get anesthetized unless you're cool with med students playing with your willy.
