Sex addiction, also known as hypersexuality, sexual compulsion, or compulsive sexual behavior, is the inability to regulate sexual thoughts or activities that negatively effect your life. Other names for sex addiction include hypersexuality, sexual compulsion, or compulsive sexual conduct. If you have a problem with sexual addiction, you might find that you have sexual fantasies, that you fantasize about having sex, or that you feel the need to engage in sexual behaviors even when it wouldn’t be proper to do so. Sexual compulsions can result in major concerns, including those relating to one’s finances, health, or legal standing.
