The typical modern man practically never thinks about sex. He dreams of it, of course, by day and by night; he craves for it; he pictures it, is stimulated or depressed by it, drools over it. But this frothing, steaming activity is not thinking. Drooling is not thinking, picturing is not thinking, craving is not thinking, dreaming is not thinking. Thinking means bringing the power of the mind to bear: thinking about sex means striving to see sex in its innermost reality and in the function it is meant to serve.
