Very short men have fewer sex partners

When two researchers at Chapman University in California began to study whether tall heterosexual men have had more sex partners than other heterosexual men, they assumed the answer would be “yes.” There was already extensive academic literature showing that height signals dominance, physical (and hence heritable) fitness, and social status to women who are seeking sex partners.

To their surprise, that’s not what they found. Tall men don’t have a history of more sex partners than men of average height or most short men, according to their study in the latest online issue of Evolutionary Psychology. After dividing respondents into different height groups, the researchers found that every group of men taller than 5 feet 4 inches had the same median number of sex partners: seven. Only men classified as “very short,” or between 5 feet 2 inches and 5 feet 4 inches, had a significantly different sexual history. They reported a median of five sex partners.
