Foucault notes that as power expands to "[take] charge of sexuality" it comes along with "a sensualization of power and a gain of pleasure"
"The medical examination, the psychiatric investigation, the pedagogical report, and family controls may have the over-all and apparent objective of saying no to all wayward or unproductive sexualities, but the fact is that they function as mechanisms with a double impetus: pleasure and power
"Power operated as a mechanism of attraction; it drew out those peculiarities over which it kept watch. Pleasure spread to the power that harried it; power anchored the pleasure it uncovered."
[see separate note from 2012]
In fact, Foucault goes so far as to say "manifold sexualities [...] all form the correlate of exact procedures of power" (47)
"Pleasure and power do not cancel or turn back against one another; they seek out, overlap and reinforce one another. They are linked together by complex mechanisms and devices of excitation and incitement." (48)
