Unsimulated sex means that real people are actually having sex on camera instead of just pretending to. When we watch a movie or TV show, sometimes they show two people kissing or hugging or doing something that could suggest they are having sex. But in unsimulated sex scenes, the actors are actually doing it for real. It's not just acting, they are actually having sex. It's important to remember that while some movies or TV shows may have unsimulated sex scenes, it is not appropriate for children to watch them.
