Heterosexuality is romantic attraction, sexual attraction or sexual behavior between persons of the opposite sex or gender. As a sexual orientation, heterosexuality is "an enduring pattern of emotional, romantic, and/or sexual attractions" to persons of the opposite sex; it "also refers to a person's sense of identity based on those attractions, related behaviors, and membership in a community of others who share those attractions." Someone who is heterosexual is commonly referred to as straight.
Group sex is sexual behavior involving more than two participants. Participants in group sex can be of any sexual orientation or gender. Any form of sexual activity can be adopted to involve more than two participants, but some forms have their own names.
A sex toy is an object or device that is primarily used to facilitate human sexual pleasure, such as a dildo or vibrator. Many popular sex toys are designed to resemble human genitals and may be vibrating or non-vibrating. The term sex toy can also include BDSM apparatus and sex furniture such as slings; however, it is not applied to items such as birth control, pornography, or condoms. Alternative expressions include adult toy and the dated euphemism marital aid, although "marital aid" has a broader sense and is applied to drugs and herbs marketed to supposedly enhance or prolong sex. Sex toys are most commonly sold at a sex shop, but they may also be sold in a pharmacy/chemist store, a pornographic DVD store, or head shop. Today's sex toys are available in almost all countries for male and females.
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.
Erotic furniture, also known as sex furniture, is any form of furniture that can act as an aid to sexual activity. While almost anything can be used for this purpose, the most common form of furniture employed for sexual activity is the bed, but couches and sofas come a close second. These are not strictly erotic furniture, as their primary use is not erotic.
Casual sex is sexual activity that takes places outside a romantic relationship and implies an absence of commitment, emotional attachment, or familiarity between sexual partners. Examples are sexual activity while casually dating, one-night stands, premarital sex, prostitution, or swinging.
Sexual addiction, also known as sex addiction, is a state characterized by compulsive participation or engagement in sexual activity, particularly sexual intercourse, despite negative consequences.
A sex swing is a type of harness designed to allow sexual intercourse between one partner suspended by the swing and another who moves freely. Though there is considerable variety in the design, the most common sex swings have a support for the back, another for the buttocks, and stirrups for each leg, which can be adjusted whilst the user is suspended.
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.
Packing is wearing padding or a phallic object in the front of the pants or underwear to give the appearance of having a penis and male bulge. Packing is commonly practiced by trans men. People who cross-dress as male may also "pack".
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 can be made from a number of materials and shaped like an erect human penis. They are typically 4–6-inch (10–15 cm) in length, about the average length of an erect penis, but some may be longer, and circumference is typically 4–5-inch (10–13 cm).
The lateral coital position is a sex position described by Masters and Johnson in their Human Sexual Response. The position was preferred by 75% of their heterosexual respondents once they had tried it.
Masturbation is the sexual stimulation of one's own genitals for sexual arousal or other sexual pleasure, usually to the point of orgasm. The stimulation may involve hands, fingers, everyday objects, sex toys such as vibrators, or combinations of these. Manual stimulation of a partner, such as fingering, a handjob or mutual masturbation, is a common sexual act and can be a substitute for penetration. Studies have found that masturbation is frequent in humans of both sexes and all ages, although there is variation. Various medical and psychological benefits have been attributed to a healthy attitude toward sexual activity in general and to masturbation in particular. No causal relationship is known between masturbation and any form of mental or physical disorder.
An orthopaedic pillow is a pillow designed to correct body positioning in bed or while lying on any other surface. Its design conforms to orthopaedic guidelines to ensure the right placement and support of one or more specific parts of the body to provide safe and healthy rest to the sleeper.
Facesitting, also known as queening or kinging, is a sexual practice in which one partner sits on or over the other's face, typically to allow or force oral–genital or oral–anal contact. In addition to oral-genital and oral-anal contact, the position also leaves the bottom partner's hands free to stimulate other erogenous zones. The top partner may be facing either direction in this position. It is common for this position to form part of BDSM, involving dominance and submission, though this need not be the case. Within a BDSM or D/s context, facesitting can be a form of erotic humiliation.
Cunnilingus is an oral sex act performed by a person on the female genitalia. The clitoris is the most sexually sensitive part of the human female genitalia, and its stimulation may result in female sexual arousal or orgasm.
Anilingus is the oral and anal sex act in which a person stimulates the anus of another by using the mouth, including lips, tongue, or teeth. It is also called anal–oral contact and anal–oral sex; colloquial names include rimming, rim job, or tossing the salad. It may be performed by and on persons of any sexual orientation for pleasure or as a form of erotic humiliation. Health risks include fecal–oral transmission of diseases.
