The most frequently reported type of incest is father-daughter incest.^[2] Incest between adults and prepubescent or adolescent children is a form of child sexual abuse^[3] that has been shown to be one of the most extreme forms of childhood trauma, a trauma that often does serious and long-term psychological damage, especially in the case of parental incest.^[4] Prevalence is difficult to generalize, but research has estimated 10-15% of the general population as having at least one incest experience, with less than 2% involving intercourse or attempted intercourse.^[5] Among women, research by Russell (1986) and Wyatt (1985) has yielded estimates as high as twenty percent.^[4]

Consensual adult incest is very rare.^[3] Consensual incest between adults is criminalized in most countries, although it is seen by some as a victimless crime.^[6]

Most societies have some form of incest avoidance.^[7][8] The incest taboo is and has been one of the most common of all cultural taboos, both in current nations and many past societies,^[9] with legal penalties imposed in some jurisdictions. Most modern societies have legal or social restrictions on closely consanguineous marriages.^[10] However, in some societies, such as that of Ancient Egypt, brother–sister, father–daughter, and mother–son relations were practiced among royalty.^[11][12] In addition, the Balinese^[13] and some Inuit tribes^[14] have altogether different beliefs about what constitutes illegal and immoral incest.

Other religions do not find sexual pleasure immoral, but see sex as a sacred, godly, highly-pleasurable activity. These traditions do not condemn sexual pleasure in and of itself, but they impose limitations on the circumstances under which sexual pleasure should be properly experienced. Pornography in this view is seen as the secularization of something sacred, and so, a violation of spouses' intimate relationship. You have heard that it was said, 'Do not commit adultery.' But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart. Paragraph 2354 of the Catechism of the Catholic Church states: Pornography... offends against chastity because it perverts the conjugal act, the intimate giving of spouses to each another. It does grave injury to the dignity of its participants... since each one becomes an object of base pleasure and illicit profit for others. It immerses all who are involved in the illusion of a fantasy world. It is a grave offense. In addition to expressing concerns about sexual immorality, some people take an anti-pornography stance claiming that viewing pornography can be addictive, leading to self-destructive behavior. Proponents of this view compare pornography addiction to alcoholism, both in asserting the seriousness of the problem and in developing treatment methods.[citation needed] Pornography addiction is a form of sexual addiction described by its proponents as a condition characterized by the overuse or abuse of pornography.[1]

General definition Pornography addiction can be defined as a psychological addiction to, or dependence upon, pornography, theoretically characterized by obsessive viewing, reading, and thinking about pornography and sexual themes to the detriment of other areas of one's own life.[2]

Stages in Pornography addiction Experts like Stephen Andert write that, for many people pornography is a problem, and it can take control of a person's life like alcohol, gambling or drugs, and "drag them kicking and screaming or voluntarily into the gutter". They further write that the "addictive and progressive ( or regressive ) nature of pornography is well documented."[4] Psychologists and Sex therapists like Dr.Kimberly Young, Dr.Victor Cline, both specializing in addiction therapy have indicate the following stages in Pornography addiction,[5][6][7] Discovery — The thrill or arousal associated with the material is encountered during this stage. This can happen accidentally or through curiosity. This stage usually refers to initial exposure rather than exposure over a prolonged period of time. There can be a rush because the event represents entering an area that is taboo, forbidden, or simply sensually arousing.[5] Experimentation/Exploration — This stage is characterized by various cognitive distortions as the person rationalizes exploring or experimenting with the material:"It's just harmless fun" or "This isn't hurting anyone". Masturbation usually accompanies this stage, powerfully reinforcing the experience.[5][8] Desensitization — As exploration and experimentation continue, desensitization takes place. In this stage, what was once shocking or atrocious is now considered normal or even mundane, thus setting the stage for escalation.[5][9] Escalation — During this stage, the material becomes rougher, kinkier, or more bizzare in order for the person to achieve the same level of arousal or rush.[5][10] Performance — Frequent exposure to the material introduces many sexual behaviors which a person may want to act out. This stage is characterized by a person mimicking behavior he has seen depicted in the pornography. In some cases, he may attempt to experiment and act out these behaviors with his spouse, or he may seek a partner outside the marriage.[11] According to Psychologists these stages are not always sequential and its is possible that and individual can experience some of the stages and not others.[5]
