The man of Earth labors, usually, in a desert of sexual starvation.
To be sure, let us not appear to blame the man of Earth. He labors, usually, in a desert of sexual starvation. Some of his most basic physical needs are often frustrated, cruelly and systematically. In such a world, where he is seldom granted more than the appearances of women, it is natural for him to become, sadly, preoccupied with mere appearances. Often he knows little more of women than these appearances, with which he is expected, culturally, to make do.
