Hey I'm back

Looking to try and respond to some of these so bare with me
"Are we talking about formally legal prostitution, or does illegal but widely tolerated and fairly openly so meet the criteria?"
Former, unless its something like Japan where its dejure illegal but the definition is so specific that it isn't illegal in virtually all legal senses.
"Also, pornography is a differently matter. Do you mean San Fernando style pornography or hentai pornography? That is difficult because these are fairly recent things. Or do you mean the same tolerance for open depictions of nudity and sex found in Hindu cultures? This is really difficulty because there are cultures quite hostile to any sort of images."
Both. Naturally the first two don't exist for most of this timeline, but setting the stage up for a culture that does accept both is more what I had in mind.
