Further, we tested whether self-reported sexual orientation correlated with sexual orientation and masculinity-femininity attributed from facial images by independent raters.
The main aim of this study was to test for possible differences in facial shape between heterosexual and homosexual men. Thus, we may predict that morphological differences between faces of homosexual and heterosexual individuals can cue to sexual orientation. Previous studies have shown that homosexual men differ from heterosexual men in several somatic traits and lay people accurately attribute sexual orientation based on facial images.
