Sex addiction, also known as compulsive sexual behavior or hypersexuality disorder, is characterized by the compulsive need to engage in sexual practices and the inability to exercise control over sexual desires and cravings. People who struggle with this addiction have an abnormally high libido and are obsessed with everything related to sex. As you can imagine, social interactions are especially tricky for people with hypersexuality since their intrusive and obsessive thoughts related to sexuality can prevent them from behaving normally. Recent studies indicate that, from a physiological and psychological perspective, sex addiction is very much like any other addiction. In other words, hypersexuality is characterized by the activation of the same reward system that prompts other addicts to engage in destructive behaviors.
