“I love you, Katherine, believe me, I'm not gay.” It is necessary to mention this statement, these days, if you love Katherine, but why is it necessary to justify your sexual orientation and how do you decide your sexual orientation? In reality, humans are animals of their desires, but unlike other animals, these desires develop under a certain social pressure. Overall, society determines the likes and dislikes of its individuals. No two companies are exactly identical to each other. Different societies influence its people in different ways. So, as a result of this social pressure, individual psychology and its behavior are defined in a special way. Society also impacts sexual orientation, which simply refers to sexual attraction between two individuals of the same or opposite sex. Sexual orientation can be homosexual, heterosexual or bisexual and the distinction between them is not very clear. Homosexuality is the expression of romantic and sexual feelings between two of the same sex while heterosexuality refers to two opposite sexes. Since the expression of feelings has different degrees and is not so simple to classify, the two extremes (homosexuality and heterosexuality) are relatively easy to classify. In reality, sexuality is a major driver of human desires and an undefined mystery. Some people believe that sexuality develops from an individual's genetic makeup and that it is simply a matter of doing what comes naturally. However, according to Leonore Tiefer, “(For humans) sex is not a natural act” (Sex is Not a Natural Act and Other Essays). In the same way that a child learns to walk with his legs, people learn to manage their sexual desires based on their culture and experience... middle of paper......s of being heterosexual in these societies . Apart from this, social norms have been dynamic over time. In conservative American society, where homosexuality was once considered a "sin," it is now considered a "disease." People have made drastic attempts to “cure” homosexuality, including castration, lobotomies, medications, hormones, hypnosis, and electroshock treatments. However, American liberal society shows flexibility towards different sexual orientations. As a matter of fact, America, on the whole, has not fully accepted the liberalism of sexual relations. Only some American states allow same-sex marriages. A gay man living in Massachusetts with his husband may not want to move to an office in Ohio where his marriage is not recognized. Therefore, social rules and cognition influence an individual's sexuality rather than a biological factor.
