BDSM is a variety of often erotic practices or roleplaying involving bondage, discipline, dominance and submission, sadomasochism, and other related interpersonal dynamics. Given the wide range of practices, some of which may be engaged in by people who do not consider themselves to be practising BDSM, inclusion in the BDSM community or subculture often is said to depend on self-identification and shared experience.
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.
Ageplay or age play is a form of roleplaying in which an individual acts or treats another as if they are a different age. Ageplay is roleplaying between adults, and involves consent from all parties. Ageplay is not necessarily sexual, but can be. Portraying any age can be the goal of ageplay, from babies to a child to the elderly. Usually this involves someone pretending to be younger than they actually are, but more rarely can involve assuming an older role.
Sexual fetishism or erotic fetishism is a sexual fixation on a nonliving object or 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 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 or S&M, is the derivation of pleasure from acts of respectively inflicting or receiving pain or humiliation. The term is named after the Marquis de Sade, a French author known for his violent and libertine works and lifestyle, and Leopold von Sacher-Masoch, an Austrian author who described masochistic tendencies in his works. Though sadomasochistic behaviours and desires do not necessarily need to be linked to sex, sadomasochism is also a definitive feature of consensual BDSM relationships.
The National Coalition for Sexual Freedom (NCSF) is an American sex-positive advocacy and educational organization founded in 1997. NCSF has over one hundred coalition partners, and over sixty supporting members. NCSF advocates on behalf of adults involved in alternative lifestyles with respect to sexuality and relationship composition, specifically for tolerance and non-discrimination of those so identified, as well as education for adults involved in such lifestyles. The organization's main office is in Baltimore, Maryland.
Erotic sexual denial is a popular form of sexual activity whereby sexual gratification for one or both partners is delayed or "denied" sexual experiences in order to increase erotic arousal and/or tension. It is commonly used as sex play within the context of a mild dominance and submission relationship, though it can also be a solo practice. When used in the context of dominance and submission, the dominant partner is often encouraged to prioritize their own sexual pleasure over that of their submissive partner. The submissive partner receives gratification from providing sexual pleasure to their partner and from the feelings of vulnerability and tension that come from having their own sexual pleasure controlled by another. The prohibited sexual experience can be narrowly or broadly defined for a specific or indeterminate length of time, depending on the practitioner. The experience withheld can be any favored or desired sexual activities, such as specific acts or positions, provided it is something the practitioner wants.

Dominance and submission (D/s) is a set of behaviors, customs, and rituals involving the submission of one person to another in an erotic episode or lifestyle. It is a subset of BDSM. This form of sexual contact and pleasure has been shown to please a minority of people.
Erotic humiliation or sexual humiliation is a consensual psychological humiliation performed in order to produce erotic excitement or sexual arousal. This can be for either the person(s) being humiliated and demeaned or the person(s) humiliating, or both. It is sometimes performed before spectators, including through pornography and webcam modeling. It may be part of BDSM and other sexual roleplay, or accompanied by the sexual stimulation of the genitals of one or both parties in the activity.
In human sexuality, kinkiness is the use of sexual practices, concepts or fantasies that are not conventional. The term derives from the idea of a "bend" in one's sexual behaviour, to contrast such behaviour with "straight" or "vanilla" sexual mores and proclivities. It is thus a colloquial term for non-normative sexual behaviour. The term "kink" has been claimed by some who practice sexual fetishism as a term or synonym for their practices, indicating a range of sexual and sexualistic practices from playful to sexual objectification and certain paraphilias. In the 21st century the term "kink", along with expressions like BDSM, leather and fetish, has become more commonly used than the term paraphilia. Some universities also feature student organizations focused on kinks, within the context of wider LGBTQ concerns.
Paraphilic infantilism, also known as adult baby, 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", or "ABs".
Omorashi, sometimes abbreviated as simply "omo", is a form of fetish subculture first categorized and predominately recognized in Japan, in which a person experiences arousal from the idea or feeling of having a full bladder and potentially wetting themselves, or from witnessing another person in that situation.
Coprophilia, also called scatophilia or scat, is the paraphilia involving sexual arousal and pleasure from feces.
Courtship disorder is a theoretical construct in sexology developed by Kurt Freund in which a certain set of paraphilias are seen as specific instances of anomalous courtship instincts in humans. The specific paraphilias are biastophilia, exhibitionism, frotteurism, telephone scatologia, and voyeurism. According to the courtship disorder hypothesis, there is a species-typical courtship process in humans consisting of four phases, and anomalies in different phases result in one of these paraphilic sexual interests. According to the theory, instead of being independent paraphilias, these sexual interests are individual symptoms of a single underlying disorder.
Barry Charles, better known as Troughman, is an Australian underground celebrity known for his paraphilia of urolagnia in toilets at Sydney gay venues in the late 1970s through 2000s.
Diaper fetishism, or nappy fetishism, is a type of garment fetish in which a person derives pleasure from themselves or partners wearing or using a diaper. Diaper fetishism can be performed on its own or incorporated into other various kinks. These kinks may include paraphilic infantilism, omorashi, and BDSM. When combined with paraphilic infantilism, the fetish is often called adult baby/diaper lover or AB/DL for short.
Sexual sadism disorder is the condition of experiencing great sexual arousal in response to the involuntary extreme pain, suffering or humiliation of other people. Several other terms are used to describe the condition, and it 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.
According to some classification systems, Sexual masochism disorder is the condition of experiencing recurring and intense sexual arousal in response to enduring moderate to 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.
