The clitoris is a female sex organ present in mammals, ostriches and a limited number of other animals. In humans, the visible portion - the glans - is at the front junction of the labia minora, above the opening of the urethra. Unlike the penis, the male homologue (equivalent) to the clitoris, it usually does not contain the distal portion of the urethra and is therefore not used for urination. The clitoris also usually lacks a reproductive function. While few animals urinate through the clitoris or use it reproductively, the spotted hyena, which has an especially large clitoris, urinates, mates, and gives birth via the organ. Some other mammals, such as lemurs and spider monkeys, also have a large clitoris.
Orgasm is the sudden discharge of accumulated sexual excitement during the sexual response cycle, resulting in rhythmic muscular contractions in the pelvic region characterized by sexual pleasure. Experienced by males and females, orgasms are controlled by the involuntary or autonomic nervous system. They are often associated with other involuntary actions, including muscular spasms in multiple areas of the body, a general euphoric sensation and, frequently, body movements and vocalizations. The period after orgasm is often a relaxing experience, attributed to the release of the neurohormones oxytocin and prolactin as well as endorphins.
The G-spot, also called the Gräfenberg spot, is characterized as an erogenous area of the vagina that, when stimulated, may lead to strong sexual arousal, powerful orgasms and potential female ejaculation. It is typically reported to be located 5–8 cm (2–3 in) up the front (anterior) vaginal wall between the vaginal opening and the urethra and is a sensitive area that may be part of the female prostate.
Female ejaculation is characterized as an expulsion of fluid from or near the vagina during or before an orgasm. It is also known colloquially as squirting or gushing, although these are considered to be different phenomena in some research publications.
A sex position is a position of the body that people use for sexual intercourse or other sexual activities. Sexual acts are generally described by the positions the participants adopt in order to perform those acts. Though sexual intercourse generally involves penetration of the body of one person by another, sex positions commonly involve penetrative or non-penetrative sexual activities.
The missionary position or man-on-top position is a sex position in which generally a woman lies on her back and a man lies on top of her while they face each other and engage in vaginal intercourse. The position may also be used for other sexual activity, such as anal sex. It is commonly associated with heterosexual sexual activity, but is also used by same-sex couples.
Woman on top, also called the cowgirl or riding position, is a group of sex positions in which a man sits or lies on his back with his legs closed, while the female partner straddles him usually in a kneeling position facing either forward or back, and either the man or woman inserts the man's erect penis into the woman's vagina or anus. The cowgirl name derives from the image of the receiving partner "riding" the partner as a cowgirl rides a bucking horse.
Doggy style, also spelled doggie style, is a sex position in which a person bends over, crouches on all fours, or lies on their abdomen, for sexual intercourse, other forms of sexual penetration or other sexual activity. Doggy style is a form of a rear-entry position, others being with the receiving partner lying on the side in the spoons sex position or the reverse cowgirl sex position. Non-penetrative sex in this position may also be regarded as doggy style. Between sex partners, usually the person in the doggy style position is passive, while the other partner is active. Either partner may be the dominant partner or the submissive partner. The passive partner is open to a variety of additional sexual activities, with the active partner being able to penetrate the vagina, the anus during anal sex, or being in a position to perform oral sex.
Sexual penetration is the insertion of a body part or other object into a body orifice, such as the vagina, anus or mouth, as part of human sexual activity or animal sexual behavior.
The female reproductive system is made up of the internal and external sex organs that function in reproduction of new offspring. In the human the female reproductive system is immature at birth and develops to maturity at puberty to be able to produce gametes, and to carry a foetus to full term. The internal sex organs are the uterus, Fallopian tubes, and ovaries. The uterus or womb accommodates the embryo which develops into the foetus. The uterus also produces vaginal and uterine secretions which help the transit of sperm to the Fallopian tubes. The ovaries produce the ova. The external sex organs are also known as the genitals and these are the organs of the vulva including the labia, clitoris, and vaginal opening. The vagina is connected to the uterus at the cervix.

The human sexual response cycle is a four-stage model of physiological responses to sexual stimulation, which, in order of their occurrence, are the excitement phase, plateau phase, orgasmic phase and resolution phase. This physiological response model was first formulated by William H. Masters and Virginia E. Johnson, in their 1966 book Human Sexual Response. Since then, other human sexual response models have been formulated.
Ben Wa balls, also known as Orgasm balls, rin-no-tama, Venus balls or Geisha balls, are small, marble-sized balls, usually hollow and containing a small weight, that roll around and are used for sexual stimulation. Available in a variety of forms, the balls may be solid, or contain clappers or chimes within. Other, larger versions made of plastic encasing lesser balls are called Duotone balls. They are used by inserting them into the vagina and using the pubococcygeus muscles to hold them in, stimulating movement and/or vibration. Ben Wa balls should not be confused with anal kegel exercisers and prostate stimulators for men: Ben Wa balls sometimes have a retrieval string or attachment of some sort, but they do not have an adequately flared base for safe anal play.
Fingering is the use of fingers or hands to sexually stimulate the vulva, vagina, or the anus. It may be done for sexual arousal or foreplay, mutual masturbation, or constitute the entire sexual encounter. To "finger oneself" is to masturbate in this manner. It is analogous to a handjob, and may be used as penetrative or non-penetrative sexual activity.
The Venus Butterfly is a term used for various sexual techniques, one of which being the subject of the 1988 book The One Hour Orgasm. It was first publicly mentioned in a 1986 episode of the American television drama L.A. Law, although a technique of the same name appears in the book The Sensuous Woman, which was first published in 1969.
Non-penetrative sex or outercourse is sexual activity that usually does not include sexual penetration. It generally excludes the penetrative aspects of vaginal, anal, or oral sexual activity, but includes various forms of sexual and non-sexual activity, such as frottage, mutual masturbation, kissing, or cuddling. Some forms of non-penetrative sex, particularly when termed outercourse, include penetrative aspects, such as penetration that may result from forms of fingering or oral sex.
Vaginal contractions are contractions of the pelvic muscles surrounding the vagina, especially the pubococcygeus muscle. Vaginal contractions are generally an involuntary muscular response to sexual stimulation, including sexual arousal, and are commonly most intense during sexual stimulation and culminating in orgasm. Though usually an involuntary response, some women can control the muscles of the vagina to perform vaginal contractions at will. Vaginal contractions enhance the sexual experience and pleasure for both parties during sexual intercourse.
The anterior fornix erogenous zone is reportedly a female erogenous zone that when stimulated can lead to rapid vaginal lubrication and arousal, sometimes without any other form of stimulation, with continued stimulation resulting in an intense orgasm.
The vulva consists of the external female sex organs. The vulva includes the mons pubis, labia majora, labia minora, clitoris, vestibular bulbs, vulval vestibule, urinary meatus, the vaginal opening, and Bartholin's and Skene's vestibular glands. The urinary meatus is also included as it opens into the vulval vestibule. Other features of the vulva include the pudendal cleft, sebaceous glands, the urogenital triangle, and pubic hair. The vulva includes the entrance to the vagina, which leads to the uterus, and provides a double layer of protection for this by the folds of the outer and inner labia. Pelvic floor muscles support the structures of the vulva. Other muscles of the urogenital triangle also give support.
Pussy torture, also known as cunt torture or vagina torture is a BDSM or sexual activity involving the application of pain or pressure to the vulva or vagina, typically in the context of sadomasochism, applied through activities such as:
