Of course they had pornography. Goya and and the Marquis de Sade both got into trouble for that.
Street prostitution was common. Concubinage was common and there were so many out of wedlock children that the foundling homes were full. My own great great grandfather did not marry my great great grandmother. They lived together.

As for modesty, consider that after the French revolution women wore thin form fitting dresses and some even wet the dresses to make the fabric cling.

In America Cardinal Hughes had to work very hard to teach his Irish flock to give up drinking, violent crime and moral vice.
There is nothing new under the sun.
