The muscular male: A comparison of the physical attractiveness preferences of gay and heterosexual men

This study examined the association between sexual orientation and the perception of men's physical attractiveness. Twenty-seven heterosexual men and 23 gay men were asked to rate, according to physical attractiveness, a series of images of real men with known body mass index (BMI) and waist-to-chest ratio (WCR). The results showed that the WCR was the primary component of attractiveness ratings for both heterosexual and gay men. However, gay men showed a stronger preference for lower WCRs, indicating a preference for a more developed upper-body build. There were small differences in terms of preference for overall body weight, with both groups preferring an image with a BMI of about 21kg/m². The findings are discussed in terms of gay culture, which emphasises the importance of muscularity in physical attraction.
