Recent research suggests that pornography consumption—especially consumption of a more hard-core or violent sort— has negative effects on individuals and society. More studies are necessary, but a growing body of research strongly suggests that for some users pornography can be psychologically addictive, and can negatively affect the quality of interpersonal relationships, sexual health and performance, and social expectations about sexual behavior. Widespread pornography consumption appears to pose a serious challenge to public health and to personal and familial well-being.
