Sex toy in the context of "Masturbation"

Anal sex or anal intercourse principally means 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, and pegging. 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.

While anal sex is commonly associated with male homosexuality, research shows that not all homosexual men engage in anal sex and that it is not uncommon in heterosexual relationships. Types of anal sex can also be part of lesbian sexual practices. People may experience pleasure from anal sex by stimulation of the anal nerve endings, and orgasm may be achieved through anal penetration – by indirect stimulation of the prostate in men, indirect stimulation of the clitoris or an area in the vagina (sometimes called the G-spot) in women, and other sensory nerves (especially the pudendal nerve). People may also find anal sex painful, sometimes extremely so, which may be due to psychological factors in some cases.

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.

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 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.

A sex position is a positioning of the bodies that people use to engage in 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 non-penetrative sexual activities.

Three broad and overlapping categories of sexual activity are commonly practiced: vaginal sex, anal sex, and oral sex (mouth-on-genital or mouth-on-anus). Sex acts may also be part of a fourth category, manual sex, which is stimulating the genitals or anus by using fingers or hands. Some acts may include stimulation by a device (sex toy), such as a dildo or vibrator. There are numerous sex positions that participants may adopt in any of these types of sex acts, and some authors have argued that the number of sex positions is essentially limitless.

Anal masturbation is an autoerotic practice in which a person masturbates by sexually stimulating their own anus and rectum. Common methods of anal masturbation include manual stimulation of the anal opening and the insertion of an object or objects. Items inserted may be sex toys such as anal beads, butt plugs, dildos, vibrators, rectal thermometers or specially designed prostate massagers or enemas.

Sexual activities involving women who have sex with women (WSW), regardless of their sexual orientation or sexual identity, can include oral sex, manual sex, or tribadism. Sex toys may be used.

Romantic or sexual interpersonal relationships are often subject to sexual desire and arousal, which then leads to sexual activity for sexual release. A physical expression of intimacy between women depends on the context of the relationship along with social, cultural and other influences. In some countries, lesbian sexual practices are criminalized alongside gay sexual practices.
