Foucault raises the interesting paradox that faces our society: sex as something that is secret and taboo, yet discussed everywhere with everyone. We are a "prude" people that talk about sex in order to make it more prude. Society has managed to "hide sex in plain sight" -see where I got my title from :) . Sex is "not a thing which stubbornly shows itself, but one which always hides, the insidious presence that speaks in a voice so muted and often disguised that one risks remaining deaf to it." (35) The fact that sex is in every movie we see, in every commercial, on the back of every t shirt, and constantly in our faces, numbs us to the fact that it is sex we are talking about. As long as we don not explicitly say sex, which would garnish whispers and giggles, we can talk about it as much as we would like. "A policing of sex: that is, not the rigor of a taboo, but the necessity of regulating sex through useful and public discourse." (25) Its so obvious as long as you know where to look.
On a completely unrelated note, what in god's name is "the game curdled milk"? (31) Apparently it is common and played by some old dude with a seven year old girl...
