Heterosexuality is romantic attraction, sexual attraction or sexual behavior between people of the opposite sex or gender. As a sexual orientation, heterosexuality is "an enduring pattern of emotional, romantic, and/or sexual attractions" to people of the opposite sex; it "also refers to a person's sense of identity based on those attractions, related behaviors, and membership in a community of others who share those attractions." Someone who is heterosexual is commonly referred to as straight.
The relationship between biology and sexual orientation is a subject of research. While scientists do not know the exact cause of sexual orientation, they theorize that it is caused by a complex interplay of genetic, hormonal, and environmental influences. Hypotheses for the impact of the post-natal social environment on sexual orientation, however, are weak, especially for males.
Gay bashing is an attack, abuse, or assault committed against a person who is perceived by the aggressor to be gay, lesbian, bisexual, or transgender (LGBT).

Joseph Nicolosi was an American clinical psychologist who advocated and practised "reparative therapy", a form of the pseudoscientific treatment of conversion therapy that he claimed could help people overcome or mitigate their homosexual desires and replace them with heterosexual ones. Nicolosi was a founder and president of the National Association for Research and Therapy of Homosexuality (NARTH). Medical institutions warn that conversion therapy is ineffective and may be harmful, and that there is no evidence that sexual orientation can be changed by such treatments.
