Heterosexuality refers to romantic and/or sexual attraction between individuals of different genders, serving as a foundational category within the classification of sexual orientations. Scholars such as Havelock Ellis examined its interaction with societal pressures, observing how suppression could lead some homosexual individuals to identify as bisexual.
Wilhelm Stekel contended that both homosexuals and heterosexuals may suppress alternative orientations, whereas Albert Moll highlighted the continuation of homosexual inclinations beyond adolescence. Legal and psychological discussions, including Anthony Kennedy’s mention of historical terminology or Mihai Nadin’s examination of biological and social influences, highlight its debated nature. These viewpoints together illustrate heterosexuality as a socially constructed standard, influenced by cultural, psychological, and biological factors.
