Young and older gay men from 40 countries rated the importance of 258 body features in judging the physical attractiveness of other men (N = 3,600). Exploratory factor analyses using two separate, independent samples suggested four factors underlying male same-sex physical attractiveness: Facial Attractiveness; Muscularity/Body Shape; Body Fat/Overall Appearance; and Intimate Regions. Twenty items representing the four dimensions were selected. Confirmatory factor analytic models using two other separate, independent samples supported the viability of a hierarchical structure with four first-order attractiveness factors mapping onto a higher-order Attractiveness construct. Responses to the scale exhibited strong internal consistency and test-retest reliability (r = .73 over an average period of 16 weeks). In addition, the hierarchical structure of responses appears to be time- and age-invariant. Results are discussed in the context of evolutionary theory.
