 The erotic wall paintings in the Suburban Baths are the only set of such art found in a public Roman bath house.Explicit sex scenes (such as group sex and oral sex) are depicted in these paintings that cannot be easily found in collections of erotic Roman art.As the sexual acts portrayed are all considered "debased" according to the customs of ancient Rome, it is possible that the intention behind their reproduction was to provide a source of humour to visitors of the building.
