[…] Sexuality is constituted in society and history, not biologically ordained. This does not mean the biological capacities are not prerequisites for human sexuality. It does mean that human sexuality is not comprehensible in purely biological terms. Human organisms with human brains are necessary for human cultures, but no examination of the body or its parts can explain the nature and variety of human social systems. The belly’s hunger gives no clues as to the complexities of cuisine. The body, the brain, the genitalia, and the capacity for language are all necessary for human sexuality. But they do not determine its content, its experiences, or its institutional forms.
