A paraphilia is an experience of recurring or intense sexual arousal to atypical objects, places, situations, fantasies, behaviors, or individuals. It has also been defined as a sexual interest in anything other than a legally consenting human partner. Paraphilias are contrasted with normophilic ("normal") sexual interests, although the definition of what makes a sexual interest normal or atypical remains controversial.
Klismaphilia, from the Greek words κλύσμα and φιλία ("love"), is a paraphilia involving enjoyment of, and sexual arousal from, enemas.
Sexual fetishism or erotic fetishism is a sexual fixation on a body part. The object of interest is called the fetish; the person who has a fetish is a fetishist. A sexual fetish may be regarded 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.
Medical fetishism refers to several sexual fetishes in which participants derive sexual pleasure from medical scenarios including objects, practices, environments, and situations of a medical or clinical nature. In sexual roleplay, a hospital or medical scene involves the sex partners assuming the roles of doctors, nurses, surgeons and patients to act out specific or general medical fetishes. Medical fantasy is a genre in pornography, though the fantasy may not necessarily involve pornography or sexual activity.
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.
Koro is a culture bound delusional disorder in which individuals have an overpowering belief that their sex organs are retracting and will disappear, despite the lack of any true longstanding changes to the genitals. Koro is also known as shrinking penis, and was listed in the Diagnostic and Statistical Manual of Mental Disorders.
Sexual dysfunction is difficulty experienced by an individual or partners during any stage of normal sexual activity, including physical pleasure, desire, preference, arousal, or orgasm. The World Health Organization defines sexual dysfunction as a "person's inability to participate in a sexual relationship as they would wish". This definition is broad and is subject to many interpretations. A diagnosis of sexual dysfunction under the DSM-5 requires a person to feel extreme distress and interpersonal strain for a minimum of six months. Sexual dysfunction can have a profound impact on an individual's perceived quality of sexual life. The term sexual disorder may not only refer to physical sexual dysfunction, but to paraphilias as well; this is sometimes termed disorder of sexual preference.
The Tanner scale is a scale of physical development as pre-pubescent children transition into adolescence, and then adulthood. The scale defines physical measurements of development based on external primary and secondary sex characteristics, such as the size of the breasts, length of the penis, volume of the testes, and growth of pubic hair. This scale was first quantified in 1969 by James Tanner, a British pediatrician, after a two-decade-long study following the physical changes in girls undergoing puberty.
Anal masturbation is an autoerotic practice in which a person masturbates by sexually stimulating their own anus and rectum. Common methods of anal masturbation include manual stimulation of the anal opening and the insertion of an object or objects. Items inserted may be sex toys such as anal beads, butt plugs, dildos, vibrators, or specially designed prostate massagers or enemas.
Formication is the sensation resembling that of small insects crawling on the skin, in the absence of actual insects. It is one specific form of a set of sensations known as paresthesias, which also include the more common prickling, tingling sensation known as pins and needles. Formication is a well-documented symptom which has numerous possible causes. The word is derived from formica, the Latin word for ant.
Hair fetishism, also known as hair partialism and trichophilia, is a partialism in which a person sees hair – most commonly, head hair – as particularly erotic and sexually arousing. Arousal may occur from seeing or touching hair, whether head hair, armpit hair, chest hair or fur. Head-hair arousal may come from seeing or touching very long or short hair, wet hair, certain colors of hair or a particular hairstyle.
Paraphilic infantilism, also known as adult baby the more inclusive non-infantile term is Adult Boy/Girl+, is a form of ageplay that involves role-playing a regression to an infant-like state. Like other forms of adult play, depending on the context and desires of the people involved paraphilic infantilism may be expressed as a non-sexual fetish, kink, or simply as a comforting platonic activity. People who practice adult baby play are often colloquially referred to as "adult babies", the more inclusive term would be "adult boys/girls+" or "ABs".
Delayed ejaculation (DE) is a man's inability or persistent difficulty in achieving orgasm, despite typical sexual desire and sexual stimulation. Generally, a man can reach orgasm within a few minutes of active thrusting during sexual intercourse, whereas a man with delayed ejaculation either does not have orgasms at all or cannot have an orgasm until after prolonged intercourse which might last for 30–45 minutes or more. Delayed ejaculation is closely related to anorgasmia.
Sexual obsessions are persistent and unrelenting thoughts about sexual activity. In the context of obsessive-compulsive disorder (OCD), these are extremely common, and can become extremely debilitating, making the person ashamed of the symptoms and reluctant to seek help. A preoccupation with sexual matters, however, does not only occur as a symptom of OCD, they may be enjoyable in other contexts.
Non-penetrative sex or outercourse is sexual activity that usually does not include sexual penetration, but some forms, particularly when termed outercourse, include penetrative aspects, that may result from forms of fingering or oral sex. It generally excludes the penetrative aspects of vaginal, anal, or oral sex, but includes various forms of sexual and non-sexual activity, such as frottage, manual sex, mutual masturbation, kissing, or hugging.
Masturbation is a form of autoeroticism in which a person sexually stimulates their own genitals for sexual arousal or other sexual pleasure, usually to the point of orgasm. Stimulation may involve use of hands, everyday objects, sex toys, or more rarely, the mouth. Masturbation may also be performed with a sex partner, either masturbating together or watching the other partner masturbate.
Buried penis, also called hidden penis or retractile penis, is a congenital or acquired condition in which the penis is partially or completely hidden below the surface of the skin. A buried penis can lead to urinary difficulties, poor hygiene, infection, and inhibition of normal sexual function.
The following outline is provided as an overview of and topical guide to human sexuality:
Animal non-reproductive sexual behavior encompasses sexual activities that non-human animals participate in which do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals, recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals. Animals have been observed to engage in sex for social interaction bonding, exchange for significant materials, affection, mentorship pairings, sexual enjoyment, or as demonstration of social rank. Observed non-procreative sexual activities include non-copulatory mounting, oral sex, genital stimulation, anal stimulation, interspecies mating, same-sex sexual interaction, and acts of affection, although it is doubted that they have done this since the beginning of their existence. There have also been observations of sex with cub participants, as well as sex with dead animals.
