Michel Foucault said this quote

People know what they do, frequently they know why they do what they do, but what they don't know is what what they do does.

~ Michel Foucault

Calling sex by its name thereafter [the 17th c.] became more difficult and more costly. As if in order to gain mastery of it in reality, it had first been necessary to subjugate it at the level of language, control its free circulation in speech, expunge it from the things that were said, and extinguish the words that rendered it too visibly present.

~ Michel Foucault

The necessity of reform mustn’t be allowed to become a form of blackmail serving to limit, reduce, or halt the exercise of criticism. Under no circumstances should one pay attention to those who tell one: “Don’t criticize, since you’re not capable of carrying out a reform.” That’s ministerial cabinet talk. Critique doesn’t have to be the premise of a deduction that concludes, “this, then, is what needs to be done.” It should be an instrument for those for who fight, those who resist and refuse what is. Its use should be in processes of conflict and confrontation, essays in refusal. It doesn’t have to lay down the law for the law. It isn’t a stage in a programming. It is a challenge directed to what is.

~ Michel Foucault

In actual fact. The manifold sexualities - those which appear with the different ages (sexualities of the infant or the child), those which become fixated on particular tastes or practices (the sexuality of the invert, the gerontophile, the fetishist), those which, in a diffuse manner, invest relationships (the sexuality of doctor and patient, teacher and student, psychiatrist and mental patient), those which haunt spaces (the sexuality of the home, the school, the prison)- all form the correlate of exact procedures of power.
