A paraphilia is an experience of recurring or intense sexual arousal to atypical objects, situations, fantasies, behaviors, or individuals. It has also been defined as a sexual interest in anything other than a consenting human partner. Paraphilias are contrasted with normophilic ("normal") sexual interests, though the definition of what makes a sexual interest normal or atypical remains controversial.
Sexual fetishism or erotic fetishism is a sexual fixation on a nonliving object or nongenital body part. The object of interest is called the fetish; the person who has a fetish for that object is a fetishist. A sexual fetish may be regarded as a non-pathological aid to sexual excitement, or as a mental disorder if it causes significant psychosocial distress for the person or has detrimental effects on important areas of their life. Sexual arousal from a particular body part can be further classified as partialism.
Sadism and masochism, known collectively as sadomasochism, are the derivation of pleasure from acts of respectively inflicting or receiving pain or humiliation. Practitioners of sadomasochism may seek sexual pleasure from their acts. While the terms sadist and masochist refer respectively to one who enjoys giving and receiving pain, some practitioners of sadomasochism may switch between activity and passivity.
Hypersexuality is a term used for a presumed mental disorder which causes unwanted or excessive sexual arousal, causing people to engage in or think about sexual activity to a point of distress or impairment. It is controversial whether it should be included as a clinical diagnosis used by mental healthcare professionals. Nymphomania and satyriasis were terms previously used for the condition in women and men, respectively.
Ephebophilia is the primary sexual interest in mid-to-late adolescents, generally ages 15 to 19. The term was originally used in the late 19th to mid-20th century. It is one of a number of sexual preferences across age groups subsumed under the technical term chronophilia.Ephebophilia strictly denotes the preference for mid-to-late adolescent sexual partners, not the mere presence of some level of sexual attraction. It is not a psychiatric diagnosis.
Hebephilia is the strong, persistent sexual interest by adults in pubescent children, typically ages 11–14 and showing Tanner stages 2 to 3 of physical development. It differs from pedophilia, and from ephebophilia. While individuals with a sexual preference for adults may have some sexual interest in pubescent-aged individuals, researchers and clinical diagnoses have proposed that hebephilia is characterized by a sexual preference for pubescent rather than adult partners.
Kurt Freund was a Czech-Canadian physician and sexologist best known for developing the penile plethysmograph, research studies in pedophilia, and for the "courtship disorder" hypothesis as a taxonomy of certain paraphilias. After unsuccessful attempts to change men's sexual orientation, he advocated against conversion therapy and in favor of the decriminalization of homosexuality.
Psychosexual disorder is a sexual problem that is psychological, rather than physiological in origin. "Psychosexual disorder" was a term used in Freudian psychology. The term of psychosexual disorder used by the TAF for homosexuality as a reason to ban the LGBT people from military service.
Richard Green was an American-British sexologist, psychiatrist, lawyer, and author known for his research on homosexuality and transsexualism, specifically gender identity disorder in children. He is known for his behaviorism experiment in which he attempted to prevent male homosexuality and transsexuality by extinguishing feminine behavior in young boys. He later came to favor biological explanations for male homosexuality.
Paraphilic infantilism, also known as autonepiophilia and adult baby, is a sexual fetish or non-sexual kink that may involve role-playing a regression to an infant-like state. Paraphilic infantilism is a form of ageplay. People who practice paraphilic infantilism are often colloquially referred to as "adult babies", or "ABs".
Androphilia and gynephilia are terms used in behavioral science to describe sexual orientation, as an alternative to a gender binary homosexual and heterosexual conceptualization. Androphilia describes sexual attraction to men and/or masculinity; gynephilia describes the sexual attraction to women and/or femininity. Ambiphilia describes the combination of both androphilia and gynephilia in a given individual, or bisexuality.
Ray Milton Blanchard is an American-Canadian sexologist who researches pedophilia, sexual orientation and gender identity. He has found that men with more older brothers are more likely to be gay than men with fewer older brothers, a phenomenon he attributes to the reaction of the mother's immune system to male fetuses. Blanchard has also published research studies on phallometry and several paraphilias, including autoerotic asphyxia. Blanchard also proposed a typology of transsexualism.
The American-Canadian sexologist Ray Blanchard proposed a psychological typology of gender dysphoria, transsexualism, and fetishistic transvestism in a series of academic papers through the 1980s and 1990s. Building on the work of earlier researchers, including his colleague Kurt Freund, Blanchard categorized trans women into two groups: homosexual transsexuals who are attracted exclusively to men and are feminine in both behavior and appearance; and autogynephilic transsexuals who experience sexual arousal at the idea of having a female body. Blanchard and his supporters argue that the typology explains differences between the two groups in childhood gender nonconformity, sexual orientation, history of sexual fetishism, and age of transition.
Pedophilia is a psychiatric disorder in which an adult or older adolescent experiences a primary or exclusive sexual attraction to prepubescent children. Although girls typically begin the process of puberty at age 10 or 11, and boys at age 11 or 12, psychiatric diagnostic criteria for pedophilia extend the cut-off point for prepubescence to age 13. People with the disorder are often referred to as pedophiles.
James M. Cantor is an American-Canadian clinical psychologist and sexologist specializing in hypersexuality and paraphilias.
Erotic target location error (ETLE) is a hypothesized dimension for paraphilias, defined by having a sexual preference or strong sexual interest in features that are somewhere other than on one's sexual partners. When one's sexual arousal is based on imagining oneself in another physical form the erotic target is said to be one's self, or erotic target identity inversion (ETII).
Michael Chikong Seto is a Canadian forensic psychologist, sexologist, and author. He is director of Forensic Rehabilitation Research at the Royal Ottawa Health Care Group, where his research focuses on pedophilia, sexual offenses committed against children, child pornography, risk assessment, offenders with mental disorders, psychopathy, and program evaluation.
Sexual sadism disorder is the condition of experiencing sexual arousal in response to the involuntary extreme pain, suffering or humiliation of others. Several other terms have been used to describe the condition, and the condition may overlap with other conditions that involve inflicting pain. It is distinct from situations in which consenting individuals use mild or simulated pain or humiliation for sexual excitement. The words sadism and sadist are derived from the French writer and libertine Marquis de Sade, who wrote several novels depicting sexualized torture and violence.
Sexual masochism disorder (SMD) is the condition of experiencing recurring and intense sexual arousal in response to enduring moderate or extreme pain, suffering, or humiliation. The Diagnostic and Statistical Manual (DSM-5) of the American Psychiatric Association indicates that a person may have a masochistic sexual interest but that the diagnosis of sexual masochism disorder would only apply to individuals who also report psychosocial difficulties because of it.
