Pre-Code sex films

"Pre-code sex films" are movies that were made a long time ago, before there were very strict rules about what could be shown or talked about in movies. In these movies, people might kiss or do other things that grown-ups do, but they wouldn't show it in a way that was too graphic or made you feel uncomfortable. Some of these movies were really popular, but then some grown-ups got worried that they might be teaching people the wrong things about love and relationships. So, they decided to make stricter rules about what could be in movies. This meant that movies made after that had to be more careful about what they showed, especially when it came to anything that might be seen as too grown-up or inappropriate for kids."
