Want to know how good sex with your new guy will be? Ladies, there's no need to get into his pants (or receive a naughty picture message) in order to learn how to find out his penis size. And forget that old wives' tale about the size of his shoes. Instead, just take a look at the length of his fingers.

It all has to do with the gap in length between a man's ring finger and index finger, say Korean researchers from Gachon University.

Believing that the "digit ratio" between those two fingers could predict penis size and length, the study authors measured the penises — while flaccid but stretched out — of 144 men.

For the curious, the length a penis that's stretched out while flaccid is believed to correlate to its size while erect. The fingers in question were also measured. The researchers found that a greater distance between the ring finger and index finger meant a longer shaft.

"According to our data... the shorter index finger than ring finger you have, the longer stretched penile length you have," Dr. Tae Beom Kim, study author and professor of urology at Gachon University, told Reuters

Exposure to prenatal hormones may be to blame for this strange correlation. Previous studies have shown that high levels of testosterone are connected to a greater difference in the two lengths. Meanwhile, females — who are exposed to more estrogen in the womb — have fingers that are close to, if not the same, in length.

The size of his penis isn't all that finger length shows; men with mismatched finger lengths were previously found to have more masculine features and be more attractive to women. Now, perhaps, they'll be more attractive because of their presumably large package.

Of course, the science behind how to find out his penis size based on the finger-penis relationship currently only holds true for Korean men, but something tells us that with the discovery of such knowledge, women everywhere will be testing the theory in no time.
