Versatiles fell somewhat between the tops and bottoms on these traits. They also reported being comparatively more masculine than bottoms. Generally, tops reported larger penises than bottoms. Tops and bottoms showed a high degree of concordance between identity and enacted behavior however, only half of versatiles reported concordant identity and behavior (i.e., wanting to be versatile and actually reporting versatile behavior). Additionally, the roles of masculinity and physical body traits (e.g., penis size, muscularity, height, hairiness, and weight) were tested as correlates of anal penetrative identity and identity-behavior concordance. We surveyed 429 men engaging in same-sex anal intercourse to investigate the degree to which anal penetrative self-identity was concordant with actual penetrative behavior. Yet, what orients men to think of themselves as tops, bottoms or versatiles is poorly understood. Sociological, psychological, and public health studies document that many gay and bisexual men may self-label by their anal penetrative role (i.e., bottom or exclusively receptive top or exclusively insertive or versatile, both receptive and insertive during anal intercourse).
