Final answer:
Heteronormativity refers to the assumption that heterosexuality is the only acceptable sexual orientation. Koedt challenged heteronormativity by critiquing the idea of the vaginal orgasm and advocating for a more inclusive understanding of human sexuality and pleasure.
Step-by-step explanation:
Heteronormativity refers to the assumption that heterosexuality is the only acceptable sexual orientation. It is the belief that heterosexuality is the norm and that all individuals should conform to traditional gender roles and expectations.
One way in which Koedt challenged heteronormativity was through her influential essay titled "The Myth of the Vaginal Orgasm." In this essay, Koedt argued against the idea that women's sexual pleasure was solely dependent on heterosexual intercourse and the achievement of a vaginal orgasm. She critiqued the heteronormative assumption that sex should be focused on male pleasure and challenged the notion that women's sexual experiences should be defined and controlled by men.
Overall, Koedt's work challenged heteronormativity by questioning societal expectations around sexuality and advocating for a more inclusive understanding of human sexuality and pleasure.
