"Overall, broad shoulders as compared to the hips were the most important factor in attractiveness ratings, accounting for 79.6 percent of the variation in these rankings, the study found. Penis size and height accounted for 6.1 percent and 5.1 percent, respectively."
"While size may matter, the findings don’t suggest that only size matters. In fact, body shape seemed to trump both height and genital endowment in determining attractiveness. Based on the women’s answers, the researcher calculated that height was as important as endowment in a male’s attractiveness, while wider shoulders and narrow hips was more important than both combined"

The abstract is mundane and boring. However, the paper says that broad shoulders is what makes a male attrative by 80%. Penis Size and height doesn't nearly matter as much.
