Porn leads to diminished satisfaction with the physical appearance and sexual performance of intimate partners. Porn leads to an enhanced sense of importance of sex without emotional involvement. Porn creates an appetite for more unusual and bizarre materials such as those depicting sadomasochism and sexual violence. Initial repulsion and boredom toward porn is overridden by engaging in increasingly bizarre sex acts with a greater variety of sexual partners. Such behavior is soon perceived as normal.
Porn leads to insensitivity towards victims of sexual violence.
Exposure to porn soon leads to a belief that such materials do not harm even children. Adolescents who were sexually molested as children often begin sexually molesting children as young as two or three years of age. The most cursory examination of the material being marketed today makes it clear why that is true. I could not describe the offensiveness of these publications without being pornographic even in this context. The use of pornography seems to be addictive and progressive in nature.
