But the hunger for touch does not always involve sex. Men in prison slap each other on the back and rub each others necks and hug and give elaborate handshakes and do strange exercises in which the men use each others body weight. It is all an excuse for touch. The condition of being a prisoner, in a point made by Foucault in his brilliant Discipline and Punish, is that of a sexless thing, and much of the experience of incarceration is the prisoners reflexive effort, as a human being, to resist that state.
