heteroseksuaalsus

Heteroseksuaalsus refers to romantic attraction, sexual attraction, or sexual behavior between people of the opposite sex or gender. It is one of the most common sexual orientations observed in humans. The term is derived from the Greek prefix "heteros" meaning "other" and the Latin word "sexus" meaning "sex." Individuals who identify as heterosexual are often referred to as straight.

The prevalence of heterosexuality has been documented across various cultures and throughout history. While societal norms and expressions of sexuality have varied, heterosexual relationships have consistently been a significant aspect of human social structures. Understanding heterosexuality involves recognizing the diversity of human attraction and the spectrum of sexual orientations that exist.

Scientific and psychological research has explored the origins and development of sexual orientation, including heterosexuality. While the exact causes are complex and likely involve a combination of genetic, hormonal, and environmental factors, heterosexuality is widely considered a natural variation of human sexuality.
