It seems that Pompeii was full of sexual art, for example, a statue of the god Pan copulating with a goat, or art works depicting an obsession with the god Priapus.
“They [artifacts] reveal a more shocking side of Pompeii. The deeper historians dig the more unsettling details emerge of an elaborate system of sex in this ancient city.”
“The clues are everywhere, from stone phalluses on public streets to crude graffiti carved into granite walls. They appear to reveal a population trading in decadence, perversion, prostitution and sexual slavery.”
Brings to mind the island community in the film The Wicker Man.
I have an old book EROS IN POMPEII about that art. I would imagine all the Roman and Greek areas had such art on constant display.
Think of the early Christians and Jews who had to live their lives seeing public displays of that.
