FAT men last longer in bed, while lean gym jocks are prone to premature ejaculation, a new study has found.

The scientific research, from Erciyes University in Turkey, found that men with excess body fat develop more female sex hormones that influence their sexual performance.

Men with high fat levels were found to have higher levels of the female sex hormone oestradiol, which disrupts the chemical balance in their body, making them last longer during sex.

The survey’s results found fat men could last an average of 7.3 minutes during love making, while others only lasted 1.8 minutes.

To find the results, researchers spent a year recording the body mass index (BMI) of more than 100 patients referred for specialist treatment.

They compared these results with 100 other male patients who lasted longer during sex.

Results concluded that the men needing treatment for premature ejaculation had lower BMI scores, meaning they were fitter.

“We found that premature ejaculators were leaner,” the report stated.

So all you skinny guys out there – science has PROVEN you guys blow your load too soon.  So… neener neener!  lol.
