Anal sex or anal intercourse is generally the insertion and thrusting of the erect penis into a person's anus, or anus and rectum, for sexual pleasure. Other forms of anal sex include anal fingering, the use of sex toys, anilingus, pegging, as well as electrostimulation and erotic torture such as figging. Although anal sex most commonly means penile–anal penetration, sources sometimes use anal intercourse to exclusively denote penile–anal penetration, and anal sex to denote any form of anal sexual activity, especially between pairings as opposed to anal masturbation.
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. In most species, the clitoris lacks any 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 or sexual climax is the sudden discharge of accumulated sexual excitement during the sexual response cycle, resulting in rhythmic, involuntary 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 usually associated with 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 typically a relaxing experience, attributed to the release of the neurohormones oxytocin and prolactin as well as endorphins.
Sexual intercourse is sexual activity involving the insertion and thrusting of the male penis inside the female vagina for sexual pleasure, reproduction, or both. This is also known as vaginal intercourse or vaginal sex. Other forms of penetrative sexual intercourse include anal sex, oral sex, fingering and penetration by use of a dildo, and vibrators These activities involve physical intimacy between two or more individuals and are usually used among humans solely for physical or emotional pleasure and can contribute to human bonding.
In mammals and other animals, the vagina is the elastic, muscular reproductive organ of the female genital tract. In humans, it extends from the vestibule to the cervix. The outer vaginal opening is normally partly covered by a thin layer of mucosal tissue called the hymen. At the deep end, the cervix bulges into the vagina. The vagina allows for copulation and birth. It also channels menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle.
The hymen is a thin piece of mucosal tissue that surrounds or partially covers the vaginal opening. A small percentage are born with hymens that are imperforate and completely obstruct the vaginal canal. It forms part of the vulva and is similar in structure to the vagina. The term comes straight from the Greek, for 'membrane'.
Body modification is the deliberate altering of the human anatomy or human physical appearance. In its broadest definition it includes skin tattooing, socially acceptable decoration, and religious rites of passage, as well as the modern primitive movement.
Sir William Osler, 1st Baronet, was a Canadian physician and one of the "Big Four" founding professors of Johns Hopkins Hospital. Osler created the first residency program for specialty training of physicians, and he was the first to bring medical students out of the lecture hall for bedside clinical training. He has frequently been described as the Father of Modern Medicine and one of the "greatest diagnosticians ever to wield a stethoscope". In addition to being a physician he was a bibliophile, historian, author, and renowned practical joker. He was passionate about medical libraries and medical history, having founded the History of Medicine Society, at the Royal Society of Medicine, London. He was also instrumental in founding the Medical Library Association of Great Britain and Ireland, and the Association of Medical Librarians along with three other people, including Margaret Charlton, the medical librarian of his alma mater, McGill University. He left his own large history of medicine library to McGill, where it became the Osler Library.
Vaginismus is a condition in which involuntary muscle spasm interferes with vaginal intercourse or other penetration of the vagina. This often results in pain with attempts at sex. Often it begins when vaginal intercourse is first attempted.
Dyspareunia is painful sexual intercourse due to medical or psychological causes. The term dyspareunia covers both female dyspareunia and male dyspareunia, but many discussions that use the term without further specification concern the female type, which is more common than the male type. In females, the pain can primarily be on the external surface of the genitalia, or deeper in the pelvis upon deep pressure against the cervix. Medically, dyspareunia is a pelvic floor dysfunction and is frequently underdiagnosed. It can affect a small portion of the vulva or vagina or be felt all over the surface. Understanding the duration, location, and nature of the pain is important in identifying the causes of the pain.
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.
Insemination is the introduction of sperm into a female's reproductive system for the purpose of impregnating, also called fertilizing, the female for sexual reproduction. The sperm is introduced into the uterus of a mammal or the oviduct of an oviparous (egg-laying) animal. In mammals, insemination normally occurs during sexual intercourse or copulation, but insemination can take place in other ways, such as by artificial insemination.
John Arthur Bennett was a U.S. Army soldier who remains the last person to be executed after a court-martial by the United States Armed Forces. The 19-year-old private was convicted of the rape and attempted murder of an 11-year-old girl in Austria. Despite last minute appeals for clemency and pleas to President John F. Kennedy by her family to spare his life, Kennedy refused; Bennett was hanged at Fort Leavenworth, Kansas in 1961.
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 sex, but includes various forms of sexual and non-sexual activity, such as frottage, manual sex, 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.
A douche is a device used to introduce a stream of water into the body for medical or hygienic reasons, or the stream of water itself. Douche usually refers to vaginal irrigation, the rinsing of the vagina, but it can also refer to the rinsing of any body cavity. A douche bag is a piece of equipment for douching—a bag for holding the fluid used in douching. To avoid transferring intestinal bacteria into the vagina, the same bag must not be used for an enema and a vaginal douche.
Teeth is a 2007 American comedy horror film written and directed by Mitchell Lichtenstein. The film stars Jess Weixler and was produced by Lichtenstein on a budget of $2 million. It premiered at the Sundance Film Festival on January 19, 2007, and received a limited release in the United States on January 18, 2008, by Roadside Attractions. Its title refers to the ancient trope of vagina dentata.
Vagina dentata describes a folk tale in which a woman's vagina is said to contain teeth, with the associated implication that sexual intercourse might result in injury, emasculation, or castration for the man involved. The topic of "vagina dentata" may also cover a rare medical condition affecting the vagina, in which case it is more accurately termed a vaginal dermoid cyst.
Postcoital bleeding (PCB) is non-menstrual vaginal bleeding that occurs during or after sexual intercourse. Though some causes are with associated pain, it is typically painless and frequently associated with intermenstrual bleeding.
Genital trauma is trauma to the genitalia.
