Orgasm or sexual climax is the sudden release of accumulated sexual excitement during the sexual response cycle, characterized by intense sexual pleasure resulting in rhythmic, involuntary muscular contractions in the pelvic region. Orgasms are controlled by the involuntary or autonomic nervous system and experienced by both males and females; the body's response includes muscular spasms, a general euphoric sensation, and, frequently, body movements and vocalizations. The period after orgasm is typically a relaxing experience, after the release of the neurohormones oxytocin and prolactin, as well as endorphins.
A wet dream, sex dream, or sleep orgasm, is a spontaneous occurrence of sexual arousal during sleep that includes ejaculation and orgasm for a male, and vaginal lubrication and/or orgasm for a female.
Coitus reservatus, also known as sexual continence, is a form of sexual intercourse in which a male does not attempt to ejaculate within his partner, avoiding the seminal emission. It is distinct from death-grip syndrome, wherein a male has no volition in his emissionless state.
Female submission or femsub is an activity or relationship in which a woman submits to the direction of a sexual partner or has her body used sexually by or for the sexual pleasure of her partner. The expression is often associated with BDSM, where submission to such activity is usually voluntarily and consensual. Submission usually involves a degree of trust by the woman in her partner. The dominant partner is usually a man, but can also be another woman, or there can be multiple dominant partners simultaneously. The submissive woman may derive sexual pleasure or emotional gratification from relinquishing control to a trusted dominant partner.
Sexual stimulation is anything that leads to sexual arousal or possibly orgasm. This thing can be physical or of other senses, and is known as a stimulus in medical studies such as physiology, hence the term stimulation.
Epididymal hypertension (EH), informally referred to as blue balls for males or blue vulva for females, is a harmless but uncomfortable sensation in the genital regions during a prolonged state of sexual arousal. It usually resolves within hours unless relieved through an orgasm.
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.
Cock and ball torture (CBT) is a sexual activity involving the application of pain or constriction to the male genitals. This may involve directly painful activities, such as genital piercing, wax play, genital spanking, squeezing, ball-busting, genital flogging, urethral play, tickle torture, erotic electrostimulation, kneeing or kicking. The recipient of such activities may receive direct physical pleasure via masochism, or emotional pleasure through erotic humiliation, or knowledge that the play is pleasing to a sadistic dominant. Many of these practices carry significant health risks.
This glossary of BDSM terms defines terms commonly used in the BDSM community.
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.
Fingering is sexual stimulation of the vulva or vagina by using the fingers. Vaginal fingering is legally and medically called digital penetration or digital penetration of the vagina. The term "digital" takes its significance from the English word 'digit', which refers to a finger, thumb, or toe. Fingering may also include the use of fingers to stimulate the anus.
A forced orgasm is consensual BDSM or kinky sexual play whereby a person consents to be forced to orgasm in a way that is beyond their control.
A strap-on dildo is a dildo designed to be worn, usually with a harness, during sexual activity. Harnesses and dildos are made in a wide variety of styles, with variations in how the harness fits the wearer, how the dildo attaches to the harness, as well as various features intended to facilitate stimulation of the wearer or a sexual partner. Strap-on dildos are most frequently used by lesbian women, but can be used by people of any gender or sexuality.
Sensation play, also known as sensual play or sensory play, is an act where senses are engaged in various ways to heighten erotic pleasure and induce sensuality. As an activity, it is meant to impart pleasurable and arousing sensations upon a partner, usually during an intimate interaction.
Chastity belts are a type of chastity device used in BDSM as part of the practice of orgasm denial, to prevent the wearer from engaging in certain types of sexual activity without the permission of the dominant, who acts as "keyholder", possessing the key that unlocks the chastity belt. Without access to the key, the wearer usually cannot take off the chastity belt or device. Dominants may also enjoy long-distance chastity with their sub by keeping the key in a third location that the chastity wearer cannot access by themself.
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.
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.
Ejaculation is the discharge of semen from the testicles through the penis and out the urethra. It is the final stage and natural objective of male sexual stimulation, and an essential component of natural conception. After forming an erection, many men emit pre-ejaculatory fluid during stimulation prior to ejaculating. Ejaculation involves involuntary contractions of the pelvic floor and is normally linked with orgasm. It is a normal part of male human sexual development.
