Sex has been, and still is, prohibited and regulated in myriad ways, and women’s sexuality in particular has been intensely constrained and policed. But Foucault’s point is worth dwelling on. We are, yet again, in a moment in which it seems to be tomorrow – a tomorrow just on the horizon, close enough to touch – that sex will be good again; a moment in which we conjure away the present and appeal to the future, armed as we are with the tools needed to undo past repression – the tools of consent, and, as we’ll see, of sex research. But speech and truth-telling are not inherently emancipatory, and neither speech nor silence is inherently liberating or oppressive. What’s more, repression can operate through the mechanisms of speech, through what Foucault called the ‘incitement to discourse.’ Consent, and its conceit of absolute clarity, places the burden of good sexual interaction on women’s behaviour – on what they want and on what they can know and say about their wants; on their ability to perform a confident sexual self in order to ensure that sex is mutually pleasurable and non-coercive. Woe betide she who does not know herself and speak that knowledge. This, as we’ll see, is dangerous.
