Q:Information: - Courtship is the period in a couple's relationship which precedes their engagement and marriage, or establishment of an agreed relationship of a more enduring kind. During courtship, a couple get to know each other and decide if there will be an engagement or other such agreement. A courtship may be an informal and private matter between two people or may be a public affair, or a formal arrangement with family approval. Traditionally, in the case of a formal engagement, it has been perceived that it is the role of a male to actively "court" or "woo" a female, thus encouraging her to understand him and her receptiveness to a proposal of marriage. - Frot (slang for frottage; ult. from the French verb "frotter", "to rub") is a non-penetrative form of male-male sexual activity that usually involves direct penis-to-penis contact. The term was popularized by gay male activists who disparaged the practice of anal sex, but has since evolved to encompass a variety of preferences for the act, which may or may not imply particular attitudes towards other sexual activities. Owing to its non-penetrative character, frot has the safe sex advantage of minimizing the transmission risk for HIV/AIDS; however, it still carries the risk of skin-to-skin sexually transmitted infections, such as HPV and pubic lice (crabs), both of which can be transmitted even when lesions are not visible. - Sexual partners are people who engage in sexual activity together. The sexual partners can be of any number, sex, gender, or sexual orientation. The sexual partners may be in a committed relationship, either on an exclusive basis or not, or engage in the sexual activity on a casual basis. They may be on intimate terms (in which case they are often referred to as "lovers") or anonymous, as in the case of sex with a stranger, a one-night stand, or a prostitute. A person can be another person's sexual partner even if the sexual activity is illegal, socially taboo, or otherwise in breach of a trust or commitment. A person may have more than one sexual partner at any one time, either as polyamory, polygamy or in contravention of convention. - A penis (plural "penises" or "penes" ) is the primary sexual organ that male animals use to inseminate sexually receptive mates (usually females and hermaphrodites respectively) during copulation. Such organs occur in many animals, both vertebrate and invertebrate, but males do not bear a penis in every animal species, and in those species in which the male does bear a so-called penis, the penes in the various species are not necessarily homologous. For example, the penis of a mammal is at most analogous to the penis of a male insect or barnacle. - 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. - Sexual stimulation is any stimulus (including bodily contact) that leads to, enhances and maintains sexual arousal, and may lead to orgasm. Although sexual arousal may arise without physical stimulation, achieving orgasm usually requires physical sexual stimulation. - A strap-on dildo (also strap-on, strapon or dildo harness) 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. - Marriage, also called matrimony or wedlock, is a socially or ritually recognized union between spouses that establishes rights and obligations between them, between them and their children, and between them and their in-laws. The definition of marriage varies according to different cultures, but it is principally an institution in which interpersonal relationships, usually sexual, are acknowledged. In some cultures, marriage is recommended or considered to be compulsory before pursuing any sexual activity. When defined broadly, marriage is considered a cultural universal. Individuals may marry for several reasons, including legal, social, libidinal, emotional, financial, spiritual, and religious purposes. Whom they marry may be influenced by socially determined rules of incest, prescriptive marriage rules, parental choice and individual desire. In some areas of the world, arranged marriage, child marriage, polygamy, and sometimes forced marriage, may be practiced as a cultural tradition. Conversely, such practices may be outlawed and penalized in parts of the world out of concerns for women's rights and because of international law. In developed parts of the world, there has been a general trend towards ensuring equal rights within marriage for women and legally recognizing the marriages of interfaith or interracial, and same-sex couples. These trends coincide with the broader human rights movement. - Animal roleplay is a form of roleplay where at least one participant plays the part of a non-human animal. As with most forms of roleplay, its uses include play and psychodrama. - Human bonding is the process of development of a close, interpersonal relationship. It most commonly takes place between family members or friends, but can also develop among groups, such as sporting teams and whenever people spend time together. Bonding is a mutual, interactive process, and is different from simple liking. - An engagement, betrothal, or fiancer is a promise to wed, and also the period of time between a marriage proposal and a marriage. During this period, a couple is said to be "betrothed," "intended", "affianced", "engaged to be married," or simply "engaged". Future brides and grooms may be called "the betrothed", a "wife-to-be" or "husband-to-be", "fiancee" or "fiance", respectively (from the French word fiancer). The duration of the courtship varies vastly, and is largely dependent on cultural norms or upon the agreement of the parties involved. - In vertebrate anatomy, the throat is the anterior part of the neck, positioned in front of the vertebra. It contains the pharynx and larynx. An important section of it is the epiglottis, which is a flap separating the esophagus from the trachea (windpipe) preventing food and drink being inhaled into the lungs. The throat contains various blood vessels, pharyngeal muscles, the nasopharyngeal tonsil, the tonsils, the palatine uvula, the trachea, the esophagus, and the vocal cords. Mammal throats consist of two bones, the hyoid bone and the clavicle. The "throat" is sometimes thought to be synonymous for the isthmus of the fauces. - Licking is the action of passing the tongue over a surface, typically either to deposit saliva onto the surface, or to collect liquid, food or minerals onto the tongue for ingestion, or to communicate with other animals. Many animals both groom themselves and eat or drink by licking. - In human sexual behavior, foreplay is a set of emotionally and physically intimate acts between two or more people meant to create sexual arousal and desire for sexual activity. Either or any of the sexual partners may indicate sexual interest to initiate foreplay, and the initiator may not be the active partner during the sexual activity. Foreplay stimulates both partners' sexuality, lowers inhibitions and increases emotional intimacy between partners, and implies a certain level of confidence and trust between the partners. In animal sexual behavior, the loose equivalent is sometimes termed 'precoital activity'. - Usenet is a worldwide distributed discussion system available on computers. It was developed from the general-purpose UUCP dial-up network architecture. Tom Truscott and Jim Ellis conceived the idea in 1979, and it was established in 1980. Users read and post messages (called "articles" or "posts", and collectively termed "news") to one or more categories, known as newsgroups. Usenet resembles a bulletin board system (BBS) in many respects and is the precursor to Internet forums that are widely used today. Discussions are threaded, as with web forums and BBSs, though posts are stored on the server sequentially. The name comes from the term "users network". - Discipline is the suppression of base desires, and is usually understood to be synonymous with self-control restraint and control. Discipline is when one uses reason to determine the best course of action regardless of one's desires, which may be the opposite of excited. Virtuous behavior can be described as when one's values are aligned with one's aims: to do what one knows is best and to do it gladly. - 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. - Fellatio (also known as fellation, and colloquially as blowjob, BJ, giving head, or sucking off) is an oral sex act involving the use of the mouth or throat, which is performed by a person on the penis of another person or oneself (autofellatio). Oral stimulation of the scrotum may also be termed "fellatio" or "tea bagging." - In human sexuality, a sex life is a sector of a person's day-to-day existence which may involve sexual activity or represent the absence of sexual activity. In general parlance, the term can have many sub-meanings and social layers, but generally includes the following: - Orgasm (from Greek "orgasmos" "excitement, swelling"; also sexual climax) 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 (known as the refractory period) is often a relaxing experience, attributed to the release of the neurohormones oxytocin and prolactin as well as endorphins (or "endogenous morphine"). - Human sexuality is the capacity of humans to have erotic experiences and responses. A person's sexual orientation can influence their sexual interest and attraction for another person. Sexuality may be experienced and expressed in a variety of ways; including thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles, and relationships. These may manifest themselves in biological, physical, emotional, social, or spiritual aspects. The biological and physical aspects of sexuality largely concern the human reproductive functions, including the human sexual response cycle and the basic biological drive that exists in all species. Physical and emotional aspects of sexuality include bonds between individuals that is expressed through profound feelings or physical manifestations of love, trust, and care. Social aspects deal with the effects of human society on one's sexuality, while spirituality concerns an individual's spiritual connection with others. Sexuality also affects and is affected by cultural, political, legal, philosophical, moral, ethical, and religious aspects of life. - Dominance and submission (also called D/s) is a set of behaviors, customs, and rituals involving the submission of one person to another in an erotic episode or lifestyle. It is a subset of BDSM. - Human sexual activity , human sexual practice or human sexual behavior 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. ) in varying patterns of frequency , for a wide variety of reasons . Sexual activity normally 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 behavior ) , or personal interactions between individuals ( for instance , foreplay or BDSM ) . Sexual activity may follow sexual arousal . Human sexual activity has sociological , cognitive , emotional , behavioral and biological aspects ; these include personal bonding , sharing emotions and the physiology of the reproductive system , sex drive , sexual intercourse and sexual behavior in all its forms . In some cultures , sexual activity is considered acceptable only within marriage , while premarital and extramarital sex are taboo . Some sexual activities are illegal either universally or in some countries or subnational jurisdictions , while some are considered contrary to the norms of certain societies or cultures . Two examples that are criminal offenses in most jurisdictions are sexual assault and sexual activity with a person below the local age of consent . - A kiss is the touch or pressing of one's lips against another person or an object. Cultural connotations of kissing vary widely. Depending on the culture and context, a kiss can express sentiments of love, passion, romance, sexual attraction, sexual activity, sexual arousal, affection, respect, greeting, friendship, peace and good luck, among many others. In some situations, a kiss is a ritual, formal or symbolic gesture indicating devotion, respect, or sacrament. The word came from Old English "cyssan" (to kiss), in turn from "coss" (a kiss). - 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 pornographic DVD store or head shop. Today's sex toys are available in almost all countries for male and females. - Sexual intercourse, or coitus or copulation, is principally the insertion and thrusting of the penis, usually when erect, into the 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 (penetration of the anus by the penis), oral sex (penetration of the mouth by the penis or oral penetration of the female genitalia), fingering (sexual penetration by the fingers), and penetration by use of a dildo (especially a strap-on dildo). These activities involve physical intimacy between two or more individuals and are usually used among humans solely for physical or emotional pleasure and commonly contribute to human bonding. - 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. Mutual masturbation (mutual manual stimulation of the genitals between partners) can be a substitute for sexual 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. - 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. - BDSM is a variety of often erotic practices or roleplaying involving bondage, discipline, dominance and submission, sadomasochism, and other related interpersonal dynamics. Given the wide range of practices, some of which may be engaged in by people who do not consider themselves as practicing BDSM, inclusion in the BDSM community or subculture is usually dependent on self-identification and shared experience. The term "BDSM" is first recorded in a Usenet posting from 1991, and is interpreted as a combination of the abbreviations B/D (Bondage and Discipline), D/s (Dominance and submission), and S/M (Sadism and Masochism). BDSM is now used as a catch-all phrase covering a wide range of activities, forms of interpersonal relationships, and distinct subcultures. BDSM communities generally welcome anyone with a non-normative streak who identifies with the community; this may include cross-dressers, body modification enthusiasts, animal roleplayers, rubber fetishists, and others. - Oral sex, sometimes referred to as oral intercourse, is sexual activity involving the stimulation of the genitalia of a person by another person using the mouth (including the lips, tongue or teeth) or throat. Cunnilingus is oral sex performed on a female, while fellatio is oral sex performed on a male. Anilingus, another form of oral sex, is oral stimulation of a person's anus. Oral stimulation of other parts of the body (as in kissing and licking) is usually not considered oral sex. - Sadomasochism is the giving or receiving pleasure from acts involving the receipt or infliction of pain or humiliation. Practitioners of sadomasochism may seek sexual gratification from their acts. While the terms sadist and masochist refer respectively to one who enjoys giving or receiving pain, practitioners of sadomasochism may switch between activity and passivity. - Body modification (or body alteration) is the deliberate altering of the human anatomy or human physical appearance. It is often done for aesthetics, sexual enhancement, rites of passage, religious beliefs, to display group membership or affiliation, to create body art, for shock value, and as self-expression, among other reasons. In its broadest definition it includes plastic surgery, socially acceptable decoration ("e.g.", common ear piercing in many societies), and religious rites of passage (e.g., circumcision in a number of cultures), as well as the modern primitive movement. - Subculture, a concept from the academic fields of sociology and cultural studies, is a group of people within a culture that differentiates itself from the parent culture to which it belongs, often maintaining some of its founding principles. - An interpersonal relationship is a strong, deep, or close association or acquaintance between two or more people that may range in duration from brief to enduring. This association may be based on inference, love, solidarity, regular business interactions, or some other type of social commitment. Interpersonal relationships are formed in the context of social, cultural and other influences. The context can and may and perhaps will vary from family or kinship relations, friendship, marriage, relations with associates, work, clubs, neighborhoods, and places of worship. They may be regulated by law, custom, or mutual agreement, and are the basis of social groups and society as a whole. - In mammals, the vagina is a muscular and tubular part of the female genital tract, which in humans extends from the vulva to the cervix. The outer vaginal opening may be partly covered by a membrane called the hymen. At the deep end, the cervix (neck of the uterus) bulges into the vagina. The vagina allows for sexual intercourse and childbirth, and channels menstrual flow, which occurs periodically as part of the menstrual cycle. - Cunnilingus is an oral sex act performed by a person on a female's genitalia (the clitoris, other parts of the vulva or the vagina). 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 (from the Latin "anus" + "-lingus", from "lingere", "to lick", variantly spelled "analingus",) is the oral and anal sex act in which a person stimulates the anus of another by using the mouth, including lips, tongue, and/or teeth. It is also called analoral contact and analoral sex; colloquial names include rimming and rim job. It may be performed by and on persons of any sexual orientation for pleasure or as a form of erotic humiliation. Etymology. The term "anilingus" was coined by sexologist Richard von Krafft-Ebing in his book "Psychopathia sexualis" (1886). - 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 fingering, the use of sex toys for anal penetration, oral sex performed on the anus (anilingus), and pegging. Though the term "anal sex" most commonly means penile-anal penetration, sources sometimes use the term "anal intercourse" to refer exclusively to penile-anal penetration, and "anal sex" to refer to any form of anal sexual activity, especially between pairings as opposed to anal masturbation. - The anus (from Latin "anus" meaning "ring", "circle") is an opening at the opposite end of an animal's digestive tract from the mouth. Its function is to control the expulsion of feces, unwanted semi-solid matter produced during digestion, which, depending on the type of animal, may include: matter which the animal cannot digest, such as bones; food material after all the nutrients have been extracted, for example cellulose or lignin; ingested matter which would be toxic if it remained in the digestive tract; and dead or excess gut bacteria and other endosymbionts.
