A man's size matters when it comes to lasting long in bed — but not in the way you might think. Researchers in Turkey say the higher a man's body mass index, the longer it takes him to orgasm. Heavier men last 7.3 minutes on average, while skinnier guys last an average of 108 seconds (a little less than two minutes). The explanation behind the longevity isn't quite as sexy as the result. Extra fat leads to higher levels of female sex hormones, which delay climax. Do you think more time is worth the weight?
