Heterosexual is that pertaining to or relating to heterosexuality. This term refers to the erotic relationship between individuals of different sex. Heterosexuality, therefore, is the opposite of homosexuality (relations erotic between individuals of the same sex) and differs from the bisexuality (erotic relationships with individuals of both sexes).

Heterosexuality is a sexual orientation characterized by desire and attraction to people of opposite sex. A heterosexual man is attracted to women, while a heterosexual woman is attracted to men.


Someone heterosexual is attracted to people of the opposite sex.

Heterosexuality, biology and society

There is a wide debate about the condition genetics or social orientation of sexual orientation. There are those who believe that individuals are born heterosexual or homosexual and that their desire follows a genetic pattern. Other people argue that sexual inclination is the product of the individual’s free choice.

In the case of human beings, reproduction is only possible through heterosexual relationships (unlike other species whose individuals are hermaphrodites). Human subsistence, therefore, requires heterosexuality and is the main argument of those who speak of the unnaturalness of homosexuality. The logic indicates that if all humans were homosexual, the sexual relations necessary for the species to reproduce would not occur.

It is known as hetero allies to subjects who, although they are heterosexual, defend the civil rights of homosexuals and promote the gender equality.

It should be noted that the notion of heterosexual is also delimited by what is considered a sexual act. In fact, there are many people who judge the sexuality simply based on the relationship they have at a certain moment, escaping from labels that accompany them in perpetuity; For example, an individual who refuses to be classified as bisexual claims to be homosexual if he is in a relationship with someone of the same gender, and heterosexual otherwise.

Beyond sexual intercourse

Outside of intimate relationships, there are numerous features of the personality that are associated with heterosexuality and are used, erroneously, as tests to rule out a person’s homosexuality. For example, the gait of a heterosexual man should show a certain stiffness and it should appear that your shoulders pull the rest of the body forward, avoiding the swing of the waist and keeping the arms down and without making any kind of smooth movement; for the heterosexual woman, what is expected by society is practically the opposite: a movement driven by the waist, performing subtle and gentle rocking and with the freedom to use her arms and head to add sensuality to her walk.

What happens if this is not respected, or if the way to move is freely chosen own body To walk? It follows almost automatically that they are homosexual individuals, generally in a derogatory tone or with a hint of grief, as if it were a disease. The man who does not exhibit the behavior that society expected of him is considered “less man”, while women are branded as “masculine.”

Some activists fight to promote the open-mindedness of the world, to get acceptance of sexual diversity; and, despite the modest changes that have been seen in recent years, no one has managed to get parents to talk openly about the possibility (inevitable, by the way) that their children will one day discover their homosexuality. It is not common for a mother to assume that her newborn child will not necessarily be heterosexual and that this aspect of his personality will emerge in the future, regardless of the toys he receives and the Colour of the clothes that are bought.
