Sexual orientation has puzzled many for thousands of years. No one becomes a homosexual any more than one becomes a heterosexual. Feelings of attraction for one sex or another becomes more aware as one grows up. Where these feelings come from and why remains a mystery. According to the American Psychological Association, sexual orientation, biological gender, gender identity, and social sex are the four elements that makes up human sexuality (APA Online, n.d.). Sexual orientation is distinguished by “an enduring emotional, romantic, sexual or affectionate attraction to individuals of a particular gender”. There are three commonly recognized categories of sexual orientation; heterosexual, homosexual, and bisexual. Heterosexuals are sexually attracted to the opposite sex, homosexuals are sexually attracted to the same sex, and bisexuals are sexually attracted to both sexes. The science of psychology requires studying human behavior in all of its diversity. Psychologists must address issues related to sexual orientation in research including straight people, gays, lesbians and bisexuals from diverse cultural backgrounds. Mental health professionals are more accepting of one’s sexual orientation. The American Psychological Association removed homosexuality from its list of mental illnesses in 1973 and so did the World Health Organization in 1993 (APA Online, n.d.). Beginning in the early 1990s, activists expressed that scientific research shows that sexual orientation is due to a genetic or hormonal cause. There have been studies that believe there is a link between one’s sexual orientation and differences in portions of the brain, genes, finger length, eye blinking and neuro-hormonal differentiation. Genes seems to be only part of the answer. The environmental aspects also play a role in one’s sexual orientation, just like it influences all behaviors.
