“Penis size does affect attractiveness,” lead author Brian Mautz, a University of Ottawa post-doctoral researcher said in an NBCNews.com interview.
Past research has seemed to indicate that women, as a group, are drawn to larger male members. But those results have been disputed as sexist, or scientifically flawed, or both.
So Mautz and his team, working at the Australian National University, designed an experiment in hopes of settling the controversy. They created 49 unique, computer-generated, nude, life-sized male figures. Each figure varied in three traits: height, shoulder-hip ratio and flaccid penis size…
“As you increase penis size, the amount of attractiveness scores gets bigger” in a linear fashion, he explained, until 7.6 centimeters, or 3 inches. After three inches, attractiveness still increased, but in smaller increments.
