Porn addiction is the mental condition that makes people watch porn, again and again, making them destroy their real sex relationships and sometimes even their professional and social life. Like any other addiction, it should be addressed and treated properly.
Sometimes people are not aware they develop adult content addiction. They just believe this is the type of entertainment they like, or maybe they are just not happy with their real sex life and want something else for themselves. Sometimes people just state they have no partner currently and that is why they watch adult content so much. They believe they stop as soon as they meet a real-life partner, but it does not happen in most cases.
