There are loads of advices to guys out there as to, while under the sheet, how to fulfill their partners' secret desires, or simply put, how to fully arouse them. These tips, one of which proclaims that the male should pay attention of the entire body of the female, not specified parts or obvious spots, are not mere mundane how-tos or nasty tricks, rather, they make sense from the point of view of evolutionary psychology.

Take the whole body theory, for instance, it represents the inclination of the male's willingness to persue a long vs short term relationship. In the case of short-term, mating is the major purpose for the male; for all other traits that attact him, however, once they are under the sheet, the wholeness of his partner is no longer as important as with the long-term. This coincide with the fact that when seeking a short-term, as in one-night-stand or prostitution, he puts relatively more emphasis on her current reproductive state(sexy) than overall quality(beauty and tenderness for instance).
