"The Purity Myth" is a concept that critiques the societal emphasis on female virginity and sexual purity. It argues that this focus can lead to harmful stereotypes and unrealistic expectations for women, often linking their worth to their sexual history. The myth perpetuates the idea that women must remain "pure" to be respected or valued in society. The term is also associated with the book by Jessica Valenti, which explores how the purity movement affects women's lives and choices. Valenti discusses the implications of this myth on issues like feminism, sexuality, and gender equality, highlighting the need for a more nuanced understanding of women's autonomy.
