If you are curious, read about the sexuality of the ancient Greeks, which was inextricably bound up with social status. From Wikipaedia:
Greek society did not distinguish sexual desire or behavior by the gender of the participants, but rather by the role that each participant played in the sex act, that of active penetrator or passive penetrated.[6] This active/passive polarization corresponded with dominant and submissive social roles: the active (penetrative) role was associated with masculinity, higher social status, and adulthood, while the passive role was associated with femininity, lower social status, and youth.
