In Gore Vidal's book "Sexually Speaking: Collected Sex Writings," he challenges the validity of labeling individuals as homosexual or heterosexual. He argues that these terms are merely descriptive of sexual behaviors rather than definitive of a person's identity. Vidal emphasizes that sexual acts themselves are commonplace and natural, suggesting that everyone engages in them regardless of how they are categorized.

This perspective shifts the focus from rigid sexual classifications to a more fluid understanding of human sexuality. By asserting that these labels don't truly define individuals, Vidal encourages a broader acceptance of diverse sexual expressions, affirming that engaging in various sexual acts is part and parcel of human experience.
