 In Pompeii, phalli and testicles engraved in the sidewalks were created to aid visitors in finding their way by pointing to the prostitution and entertainment district as well as general decoration.The Romans considered depictions of sex to be decoration in good taste, and indeed the pictures reflect the sexual mores and practices of their culture, as on the Warren Cup.Sex acts that were considered taboo (such as those that defiled the purity of the mouth) were depicted in baths for comic effect.
