The body is the place where the dimensions of space, time, subjectivity and objectivity meet and interact. These dimensions are considered with regard to eating, sleeping and sex within the couple. When a disfunctioning appears in one of these three fundamental aspects, it is, in general, treated alone. Eating, sleeping and sex are, on the contrary, interdependant, and in this perspective, a therapeutical intervention on one of these vital functions can lead to an amelioration of another one of them.
