True, most cases don't have a good ending and the videos are produced especially the ones with the face of the woman shown. Nevertheless it has increasingly turned into a fantasy between couples, and I know many people dream of it even if they don't do it.
The vast majority of these videos were professionally produced between 10-20 years ago. It's a fantasy based entirely on propaganda and relies on a steady consumption of more of that propaganda. Nobody that takes this fantasy into the real world leads a successful marriage or much of a life afterwards. It's a dead end, like the people everyone in all of these video comment sections is pretending to worship.
