Heterosexuality is romantic attraction, sexual attraction or sexual behavior between persons of the opposite sex or gender. Along with bisexuality and homosexualityheterosexuality is one of the three main categories of sexual orientation within the heterosexual—homosexual continuum.
The term heterosexual or heterosexuality is usually applied to humansbut heterosexual behavior is observed in all mammals and in other animals. The term " heterosexual "Preferentemente heterosexual definition" was first published in in C.

The colloquial shortening "hetero" is attested from The abstract noun "heterosexuality" is first recorded in current use of the term heterosexual has its roots in the broader 19th century tradition of personality taxonomy.
It continues to influence the development of the modern concept of sexual orientation, and can be used to describe individuals' sexual orientation, sexual history, or self-identification.
Some reject the term heterosexualas they feel that the word only refers to one's sexual behavior and does not refer to non-sexual romantic feelings. Preferentemente heterosexual definition term heterosexual is suggested to have come into use as a neologism after, and opposite to, the word homosexual by Karl Maria Kertbeny in In LGBT slang, the term breeder has been used as a denigrating phrase to deride heterosexuals.
Hyponyms of heterosexual include heteroflexible.
The word can be informally  shortened to "hetero". One of the first uses of the word in this way was in by author G. It is now simply a colloquial term for "heterosexual", having changed in primary meaning over time. Some object to usage of the term straight because it implies that non-heteros are crooked. Heterosexual symbolism dates back to the earliest artifacts of humanity, with gender symbolsritual fertility carvings, and primitive art. This was later expressed in the symbolism of fertility rites and polytheistic worshipwhich often included images of human reproductive organssuch as lingam in Hinduism.
Modern symbols of heterosexuality in societies derived from European traditions still reference symbols used in these ancient beliefs. One such image is a combination of the symbol for Marsthe Roman god of
Preferentemente heterosexual definition, as the definitive male symbol of masculinity, and Venusthe Roman goddess Preferentemente heterosexual definition love and beauty, as the definitive female symbol of femininity. Judeo-Christian tradition has several scriptures related to heterosexuality.
The Genesis states that God created man because "it is not good that the man should be alone; I will make him an help meet for him. Now for the matters you wrote about: It is good for a man not to marry. But since there is so much immorality, each man should have his own wife, and each woman her own husband. The husband should fulfill his marital duty to his wife, and likewise the wife to her husband.
The wife's body does not belong to her alone but also to her husband. In the same way, the husband's body does not belong to him alone but also to his wife. Do not deprive each other except by mutual consent and for a time, so that you may devote yourselves to prayer.
Then come together again so that Satan will not tempt you because of your lack of self-control. I say this as a concession, not as a command. For the most part, religious traditions in the world reserve marriage to heterosexual unions, but there are exceptions including certain Buddhist and Hindu traditions, Unitarian UniversalistMetropolitan Community Church and some Anglican dioceses and some QuakerUnited Church of Canada and Reform and Conservative Jewish congregations.
Almost all religions believe that lawful sex between a man and a woman is allowed, but there are a few that believe that it is a sin, such as The ShakersThe Harmony Societyand The Ephrata Cloister. These religions tend to view all sexual relations as sinfuland promote celibacy. Other religions view heterosexual relationships as being inferior to celibacy. Some religions require celibacy for certain roles, such as Catholic priests ; however, the Catholic Church also views heterosexual marriage Preferentemente heterosexual definition sacred and necessary.
The demographics of sexual orientation are difficult to establish due to a lack of reliable data. However, the history of human sexuality shows that attitudes and behavior have varied across societies. An October Gallup poll provided unprecedented demographic information about those who identify as heterosexual, arriving at the conclusion that In a Yougov survey of 1, adults of the United Kingdom The relationship between biology and sexual orientation is a subject of research.
No simple and singular determinant for sexual orientation has been conclusively demonstrated; various studies point to different, even conflicting positions, but scientists hypothesize that a combination of genetic, hormonal, and social factors determine sexual orientation.
The neurobiology of the masculinization of the
Preferentemente heterosexual definition is fairly well understood. If there are few androgen receptors people with androgen insensitivity
Preferentemente heterosexual definition or too much androgen females with congenital adrenal hyperplasiathere can be physical and psychological effects.
Most sexual reproduction in the animal world is facilitated through opposite-sex sexual activity, although there are also animals that reproduce asexuallyincluding protozoa and lower invertebrates. Reproductive sex not necessarily require a heterosexual orientation, since orientation refers to a long-term enduring pattern of sexual and emotional attraction leading "Preferentemente heterosexual definition" to long-term social bonding, while reproductive sex requires only the basic Preferentemente heterosexual definition of intercourse only to fertile the ovum by spermoften done one time only.
At the beginning of the 20th century, early theoretical discussions in the field of psychoanalysis posited original bisexuality in human psychological development.
Quantitative studies by Alfred Kinsey in the s and Dr. Fritz Klein 's sexual orientation grid in the s find distributions similar to those postulated by their predecessors. According to Sexual Behavior in the Human Male by Alfred Kinsey and several other modern studies, the majority of humans have had both heterosexual and homosexual experiences or sensations and are bisexual.
Kinsey himself, along with current sex therapists, focused on the historicity and fluidity of sexual orientation. Kinsey's studies consistently found orientation to be something that evolves in many directions over a person's lifetime; rarely, but not necessarily, including forming attractions to a new sex.
Rarely do individuals radically reorient their sexualities rapidly—and still less do they do so volitionally—but often sexualities expand, shift, and absorb new elements over decades.
For Preferentemente heterosexual definition, socially normative "age-appropriate" sexuality requires a shifting object of attraction especially in the passage through adolescence. Contemporary queer theoryincorporating many ideas from social constructionismtends to look at sexuality as something that has meaning only within a given historical framework.
Sexuality, then, is seen as a participation in a larger social discourse and, though in some sense fluid, not as something strictly determinable by the individual.
Other studies have disputed Kinsey's methodology. Sexologists have attributed discrepancies in some findings to negative societal attitudes towards a particular sexual orientation. For example, people may state different sexual orientations depending on whether their immediate social environment is public or private. Reluctance to disclose one's actual sexual orientation is often referred to as "being in the closet. The considerable " nature and nurture " debate exists over whether predominantly biological or psychological factors produce sexual orientation in humans, or whether both significantly factor into sexual orientation.
Candidate factors include genesthe exposure of fetuses to certain hormones or lack Preferentemente heterosexual definition and environmental factors. The studies performed in order Preferentemente heterosexual definition find the origin of sexual orientation have been criticized for being too limited in scope, mostly for focusing only on heterosexuality and homosexuality as two diametrically opposite poles with no orientation in between.
It is also asserted that scientific studies focus too much on the search for a biological
Preferentemente heterosexual definition for sexual orientation, and not enough on the combined effects of both biology and psychology. In a brief by the Council for Responsible Genetics it was stated that sexual orientation is not fixed either way, and on the discourse over sexual orientation: Yet just like intelligence, sexuality is a complex human feature that modern science is attempting to explain with genetics.
Research on brain size, hormone levels, finger length, and other biological traits have yet to yield evidence for this, however. It is important to note that traits such as these result from a combination of gene expression and developmental and other environmental factors. Rather than determining that this results from purely biological processes, a trait evolves from developmental processes that Preferentemente heterosexual definition both biological and social elements.
Often, sexual orientation and sexual orientation identity are not distinguished, which can impact accurately assessing sexual identity and whether or not sexual orientation is able to change; sexual orientation identity can change throughout an individual's life, and may or may not align with biological sex, sexual behavior or actual sexual orientation. For men, a change occurred Preferentemente heterosexual definition 0.
For women, a change occurred in 1. The researchers suggested that heterosexuality may be a more stable identity because of its normative status. A 2-year study by Lisa M. Diamond on a sample of 80 non-heterosexual female adolescents age reported that half of the
Preferentemente heterosexual definition had changed sexual-minority identities more than once, one third of them during the 2-year follow-up.
Diamond concluded that "although sexual attractions appear fairly stable, sexual identities and behaviors are more fluid. In a study, the female subjects both gay and straight women became strongly sexually aroused when they viewed heterosexual as well
Preferentemente heterosexual definition lesbian erotic films. Among the male subjects, however, the straight men were more turned on by erotic films with women, the gay ones more by those with men. The study's senior researcher said that women's sexual desire is less rigidly directed toward a particular sex, as compared with men's, and it is more changeable over time.
Gay men showed some level of genital arousal to female stimuli and straight men showed some level of genital arousal to male stimuli. Heteroflexibility is a form of a sexual orientation or situational sexual behavior characterized by minimal homosexual activity in an otherwise primarily heterosexual orientation that is considered to distinguish it from bisexuality.
It has been characterized as "mostly straight".
Sexual orientation change efforts are methods that aim to change sexual orientation, used to try to convert homosexual and bisexual people to heterosexuality.
Scientists and mental health professionals generally do not believe that sexual orientation is a choice.
