1. A Bigger Belly
For men, size does matter when it comes to sex, but not what you think. The bigger the belly, the better the lover, according to a 2010 study published in The Journal of Sexual Medicine. Overweight men with obvious bellies lasted an average of 7.3 minutes compared to their thinner counterparts who could barely make it to two minutes. Although this seems counter-intuitive, the researchers found more belly fat means the man has more estradiol, the female sex hormone, which helps inhibit orgasm.
