Male Homosexuality
Human male sexuality encompasses a wide variety of feelings and behaviors. Men's feelings of attraction may be caused by various physical and social traits of their potential partner. Men's sexual behavior can be affected by many factors, including evolved predispositions, individual personality, upbringing, and culture. While most men are heterosexual, and attracted only to women, there are minorities of homosexual men and varying degrees of bisexual men. Sexual attraction Physical factors Research indicates that men tend to be attracted to young women with bodily symmetry. Facial symmetry, femininity, and averageness are also linked with attractiveness. Men typically find female breasts attractive and this holds true for a variety of cultures. The pigmentation of nipples and breasts appears to be the most important quality of breast attractiveness. Men rated women with dark nipples and dark areola as significantly more attractive than those with light-colored nipples ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Attraction
Sexual attraction is attraction on the basis of sexual desire or the quality of arousing such interest. Sexual attractiveness or sex appeal is an individual's ability to attract other people sexually, and is a factor in sexual selection or mate choice. The attraction can be to the physical or other qualities or traits of a person, or to such qualities in the context where they appear. The attraction may be to a person's aesthetics, movements, voice, among other things. The attraction may be enhanced by a person's body odor, sex pheromones, adornments, clothing, perfume or hair style. It can be influenced by individual genetic, psychological, or cultural factors, or to other, more amorphous qualities. Sexual attraction is also a response to another person that depends on a combination of the person possessing the traits and on the criteria of the person who is attracted. Though attempts have been made to devise objective criteria of sexual attractiveness and measure it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Mating Strategies
In evolutionary psychology and behavioral ecology, human mating strategies are a set of behaviors used by individuals to select, attract, and retain mates. Mating strategies overlap with reproductive strategies, which encompass a broader set of behaviors involving the timing of reproduction and the trade-off between quantity and quality of offspring. Relative to those of other animals, human mating strategies are unique in their relationship with cultural variables such as the institution of marriage. Humans may seek out individuals with the intention of forming a long-term intimate relationship, marriage, casual relationship, or friendship. The human desire for companionship is one of the strongest human drives. It is an innate feature of human nature and may be related to the sex drive. The human mating process encompasses the social and cultural processes whereby one person may meet another to assess suitability, the courtship process and the process of forming an interperso ...

Sexual Selection
Sexual selection is a mechanism of evolution in which members of one sex mate choice, choose mates of the other sex to mating, mate with (intersexual selection), and compete with members of the same sex for access to members of the opposite sex (intrasexual selection). These two forms of selection mean that some individuals have greater reproductive success than others within a population, for example because they are more Animal sexual behaviour, attractive or prefer more attractive partners to produce offspring. Successful males benefit from frequent mating and monopolizing access to one or more fertile females. Females can maximise the return on the energy they invest in reproduction by selecting and mating with the best males. The concept was first articulated by Charles Darwin who wrote of a "second agency" other than natural selection, in which competition between mate candidates could lead to speciation. The theory was given a mathematical basis by Ronald Fisher in the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parental Investment
Parental investment, in evolutionary biology and evolutionary psychology, is any parental expenditure (e.g. time, energy, resources) that benefits offspring.Clutton-Brock, T.H. 1991. ''The Evolution of Parental Care''. Princeton, NJ: Princeton U. Press. pg. 9Trivers, R.L. (1972). Parental investment and sexual selection. In B. Campbell (Ed.), ''Sexual selection and the descent of man'', 1871-1971 (pp. 136–179). Chicago, IL: Aldine. . Parental investment may be performed by both males and females (called ''biparental care''), females alone (''exclusive maternal care'') or males alone (''exclusive paternal care''). Care can be provided at any stage of the offspring's life, from pre-natal (e.g. egg guarding and Egg incubation, incubation in birds, and placental nourishment in mammals) to post-natal (e.g. food provisioning and protection of offspring). Parental investment theory, a term coined by Robert Trivers in 1972, predicts that the sex that invests more in its offsprin ...

Waist–hip Ratio
The waist–hip ratio or waist-to-hip ratio (WHR) is the dimensionless ratio of the circumference of the waist to that of the hips. This is calculated as waist measurement divided by hip measurement (). For example, a person with a 75 cm waist and 95 cm hips (or a 30-inch waist and 38-inch hips) has WHR of about 0.79. The WHR has been used as an indicator or measure of health, fertility, and the risk of developing serious health conditions. WHR correlates with perceptions of physical attractiveness. Measurement WHO protocol According to the World Health Organization's data gathering protocol, the waist circumference should be measured at the midpoint between the lower margin of the last palpable ribs and the top of the iliac crest, using a stretch-resistant tape that provides constant tension. Hip circumference should be measured around the widest portion of the buttocks, with the tape parallel to the floor. Other organizations use slightly different standards. The United ...

Sociosexual Orientation
Sociosexuality, sometimes called sociosexual orientation, is the individual difference in the willingness to engage in sexual activity outside of a committed relationship. Individuals who are more ''restricted'' sociosexually are less willing to engage in casual sex; they prefer greater love, commitment and emotional closeness before having sex with romantic partners. Individuals who are more ''unrestricted'' sociosexually are more willing to have casual sex and are more comfortable engaging in sex without love, commitment or closeness. Measurement The revised Sociosexual Orientation Inventory (SOI-R) was designed to measure sociosexuality, with high SOI scores corresponding to an unrestricted orientation and low SOI scores denoting a more restricted orientation. The SOI-R also allows for the separate assessment of three facets of sociosexuality: behavior, attitude and desire. Gender differences and sexual orientation Men tend to have higher SOI scores and be more unrestricted th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The requirement of physical contact also creates the risk of transferring infections. Prostitution is sometimes described as sexual services, commercial sex or, colloquially, hooking. It is sometimes referred to euphemistically as "the world's oldest profession" in the English-speaking world. A person who works in the field is usually called a prostitute or ''sex worker'', but other words, such as hooker and whore, are sometimes used pejoratively to refer to those who work in prostitution.

Hookup Culture
Hookup culture is one that accepts and encourages casual sex encounters, including one-night stands and other related activity, without necessarily including emotional intimacy, bonding or a committed relationship. It is generally associated with Western late adolescent sexuality and, in particular, United States college culture. The term hookup has an ambiguous definition because it can indicate kissing or any form of physical sexual activity between sexual partners. The term has been widely used in the U.S. since at least 2000. It has also been called nonrelationship sex, or sex without dating. Most research on hookups has been focused on U.S. college students, but hookups are not limited to college campuses. Adolescents and emerging adults engage in hookups for a variety of reasons, which may range from instant physical gratification, to fulfillment of emotional needs, to using it as a means of finding a long-term romantic partner.

Affair
An affair is a relationship typically between two people, one or both of whom are either married or in a long-term Monogamy, monogamous or emotionally-exclusive relationship with someone else.

Romantic relationships are considered to be contracts. They may be a formal one like marriage – consisting of both a verbal and written contract, or an informal one – consisting of only a verbal contract.

Clandestine affairs commonly cause feelings of betrayal to the other person in the primary relationship. Ironically, affairs themselves are also contracted relationships and come with numerous stipulati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
