Post-apocalyptic scenarios explored in X-rated movies

Movies, TV shows, video games and other media like to explore post-apocalyptic worlds for interesting stories. The same goes for porn movies.
This year, there have been at least five post-apocalyptic porn movies released. They include “Don’t Panic!” from Pure Taboo and “Wastelands” from Girlsway.
A search of online resources such as the Internet Adult Film Database uncovers at least 17 porn movies set after apocalyptic events. Most take place in a desert landscape like that of the “Mad Max” films. (By the way, I haven’t seen any of these movies, I’m just going by the descriptions and cover art.)
