Quizplus · Accepted Answer

The dual categorization of sexuality as either homosexual or heterosexual can be traced back to Western cultural history. This binary view of sexuality was gradually developed in Europe during the 19th and 20th centuries, and it eventually spread to other parts of the world through globalization. This binary view might not be universal across different cultures and societies since there are other ethical and cultural norms about sexuality as well.
