Sexual addiction is when someone feels like they have to have sex or do sexual things all the time, even if they don't want to or it's not good for them. It's like being addicted to candy or playing video games.
Just like with other addictions, people can't control their urges to have sex or do sexual things, even if they want to stop. This can cause problems in their relationships or at work, and can even get in the way of other important things they need to do.
People who have a sexual addiction might feel guilty, ashamed, or embarrassed about their behaviors. It's important for them to seek professional help if they're feeling out of control or if their behavior is causing problems in their life.
