Masturbation in the context of Sexual behaviour

A sanatorium (from Latin sānāre 'to heal'), also sanitarium or sanitorium, is a historic name for a specialised hospital for the treatment of specific diseases, related ailments, and convalescence.

Sanatoria were often in a healthy climate, usually in the countryside. The idea of healing was an important reason for the historical wave of establishments of sanatoria, especially at the end of the 19th and early 20th centuries. The most common issue treated at sanatoria was tuberculosis (before the discovery of antibiotics). Some sanatoria also treated alcoholism as well as hysteria, masturbation, fatigue and emotional exhaustion. Facility operators were often charitable associations, such as the Order of St. John and the newly founded social welfare insurance companies.

In Greek mythology, a satyr (Ancient Greek: σάτυρος, romanized: sátyros, pronounced [sátyros]), also known as a silenus or silenos (Ancient Greek: σειληνός, romanized: seilēnós [seːlɛːnós]), and sileni (plural), is a male nature spirit with ears and a tail resembling those of a horse, as well as a permanent, exaggerated erection. Early artistic representations sometimes include horse-like legs, but, by the sixth century BC, they were more often represented with human legs. Comically hideous, they have mane-like hair, bestial faces, and snub noses and they always are shown naked. Satyrs were characterized by their ribaldry and were known as lovers of wine, music, dancing, and women. They were companions of the god Dionysus and were believed to inhabit remote locales, such as woodlands, mountains, and pastures. They often attempted to seduce or rape nymphs and mortal women alike, usually with little success. They are sometimes shown masturbating or engaging in bestiality.

In classical Athens, satyrs made up the chorus in a genre of play known as a "satyr play", which was a parody of tragedy and known for its bawdy and obscene humor. The only complete surviving play of this genre is Cyclops by Euripides, although a significant portion of Sophocles's Ichneutae has also survived. In mythology, the satyr Marsyas is said to have challenged the god Apollo to a musical contest and been flayed alive for his hubris. Although superficially ridiculous, satyrs were also thought to possess useful knowledge, if they could be coaxed into revealing it. The satyr Silenus was the tutor of the young Dionysus, and a story from Ionia told of a silenos who gave sound advice when captured.

A sexual fantasy, or erotic fantasy, is an autoerotic mental image or pattern of thought that stirs a person's sexuality and can create or enhance sexual arousal. A sexual fantasy can be created by the person's imagination or memory, and may be triggered autonomously or by external stimulation such as erotic literature or pornography, a physical object, or sexual attraction to another person. Anything that may give rise to sexual arousal may also produce a sexual fantasy, and sexual arousal may in turn give rise to fantasies.

Sexual fantasies are nearly universal, being reported in many societies across the globe. However, because of the nature of some fantasies, the actual putting of such fantasies into action is far less common, due to cultural, social, moral, and religious constraints. In some cases, even a discussion by a person of sexual fantasies is subject to social taboos and inhibitions. Some people find it convenient to act out fantasies through sexual roleplay. A fantasy may be a positive or negative experience, or even both. It may be in response to a past experience and can influence future sexual behavior. A person may not wish to enact a sexual fantasy in real life, and since the process is entirely imaginary, they are not limited to acceptable or practical fantasies, which can provide information on the psychological processes behind sexual behavior.

Ancient Egyptian creation myths are the ancient Egyptian accounts of the creation of the world. The Pyramid Texts, tomb wall decorations, and writings, dating back to the Old Kingdom (c. 2700–2200 BC) have provided the majority of information regarding ancient Egyptian creation myths. These myths also form the earliest recorded religious compilations in the world.

The ancient Egyptians had many creator gods and associated legends. Thus, the world or more specifically Egypt was created in diverse ways according to different parts of ancient Egypt. Some versions of the myth indicate spitting, others masturbation, as the act of creation. The earliest god, Ra and/or Atum (both being creator/sun gods), emerged from a chaotic state of the world and gave rise to Shu (air) and Tefnut (moisture), from whose union came Geb (earth) and Nut (sky), who in turn created Osiris, Isis, Set, and Nephthys. An extension to this basic framework was the Osiris myth involving Osiris, his consort Isis, and their son Horus. The murder of Osiris by Set, and the resulting struggle for power, won by Horus, provided a powerful narrative linking the ancient Egyptian ideology of kingship with the creation of the cosmos.

Human sexual activity, human sexual practice or human sexual behaviour is the manner in which humans experience and express their sexuality. People engage in a variety of sexual acts, ranging from activities done alone (e.g., masturbation) to acts with another person (e.g., sexual intercourse, non-penetrative sex, oral sex, etc.) or persons (e.g., orgy) in varying patterns of frequency, for a wide variety of reasons. Sexual activity usually results in sexual arousal and physiological changes in the aroused person, some of which are pronounced while others are more subtle. Sexual activity may also include conduct and activities which are intended to arouse the sexual interest of another or enhance the sex life of another, such as strategies to find or attract partners (courtship and display behaviour), or personal interactions between individuals (for instance, foreplay or BDSM). Sexual activity may follow sexual arousal.

Human sexual activity has sociological, cognitive, emotional, behavioural and biological aspects. It involves personal bonding, sharing emotions, the physiology of the reproductive system, sex drive, sexual intercourse, and sexual behaviour in all its forms.

Autoeroticism (also known as autoerotism or self-gratification) is sexual activity involving only one participant. It is the use of one's own body and mind to stimulate oneself sexually.

As an extension of masturbation, it usually means one of several activities done by oneself to fulfill their own sexual desire. Masturbation has a similar meaning, but is not synonymous; masturbation is only physical stimulation of the genitals by oneself while autoeroticism encompasses all stimulation by oneself (masturbation or sexual thoughts), as well as involuntary experiences (wet dreams or spontaneous sexual arousal).

Sexual stimulation is anything that leads to sexual arousal or orgasm. This thing can be physical or of other senses, and is known as a stimulus.

Sexual stimulation is a broad term, usually understood to mean physical touching of the genitals or other body parts. The term can, however, include stimuli affecting the mind (sexual fantasy), or senses other than touch (such as sight, smell, or hearing). Sufficient physical stimulation of the genitals usually results in an orgasm. Stimulation can be by oneself (masturbation or sexual fantasy) or by a sexual partner (sexual intercourse or other sexual activity), by use of objects or tools, or by some combination of these methods.

Orgasm (from Greek ὀργασμός, orgasmos; "excitement, swelling"), sexual climax, or simply 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 are experienced by both males and females; the body's response includes muscular spasms (in multiple areas), a general euphoric sensation, and, frequently, body movements and vocalizations. The period after orgasm (known as the resolution phase) is typically a relaxing experience due to the release of the neurohormones oxytocin and prolactin, as well as endorphins (or "endogenous morphine").

Human orgasms usually result from physical sexual stimulation of the penis in males (typically accompanied by ejaculation) and of the clitoris (and vagina) in females. Sexual stimulation can be by masturbation or with a sexual partner (penetrative sex, non-penetrative sex, or other sexual activity). Physical stimulation is not a requisite, as it is possible to reach orgasm through psychological means. Getting to orgasm may be difficult without a suitable psychological state. During sleep, a sex dream can trigger an orgasm and the release of sexual fluids (nocturnal emission).

Autofellatio is a form of masturbation involving the oral stimulation of one's own penis. Performing fellatio on oneself is rare due to the flexibility required. Some have publicly documented training methods through online media, suggesting the act is generally attainable with consistent physical conditioning.

Autocunnilingus is a form of masturbation involving the oral stimulation of one's own vulva. Performing cunnilingus on oneself requires an unusually high degree of flexibility such as that of contortionists or double-jointed people.

Fingering is sexual stimulation of the vulva (including the clitoris) 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.When someone performs fingering on another person's vulva or vagina, it is a form of manual sex, and is analogous to a handjob (manual stimulation of the penis). It may be used for sexual arousal or foreplay, constitute an entire sexual encounter, or be used as non-penetrative sexual activity. Fingering performed on one's own vulva or vagina is a form of masturbation.

A dildo is a sex toy, often explicitly phallic in appearance, intended for sexual penetration or other sexual activity during masturbation or with sex partners. Dildos are made from a number of materials. The shape and size are typically that of a human penis, but there is a wide variation to accommodate the needs of different users.

A strap-on dildo (also simply a strap-on) 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 can be used by people of any gender or sexuality.

A strap-on dildo can be used for a wide variety of sexual activities, including vaginal sex, anal sex, pegging, oral sex, or masturbation. Sexual lubricant can be used to ease insertion.

A vibrator, sometimes described as a massager, is a sex toy that is used on the body to produce pleasurable sexual stimulation. There are many different shapes and models of vibrators. Most modern vibrators contain an electric-powered device that pulsates or throbs. Vibrators can be used for both solo play and partnered play by one or more people. Devices exist to be used by couples to stimulate the genitals of both partners. They can be applied to erogenous zones – such as the vulva, vagina, penis, scrotum, anus, or rectum – for sexual stimulation, for the release of sexual frustration, and to achieve orgasm. Vibrators may be recommended by sex therapists for women who have difficulty reaching orgasm through masturbation or intercourse.
