Good news, Jon Hamm. According to a new report published by the Proceedings of the National Academy of Sciences, the larger a man’s penis, the more attractive he is to women. The study—led by postdoctoral fellow Brian Mautz—presented short video clips of naked, computer-generated men to 105 Australian women. The clips displayed males with varying heights, body shapes, and flaccid penis sizes, but with similar facial attractiveness and hair. The womens’ 1–7 ratings presented a clear connection between penis size and male attractiveness. To be fair, it wasn’t the only thing the women were looking at, with shoulder-to-hip ratio accounting for the biggest variance.
