I would like to add that whenever a young man shaves or a young girl makes up her face, or either of them puts on attractive clothes, it is done for the implicit purpose of arousing sexual thoughts and desires—which does not mean the intention of rushing to bed with every stranger, but merely the wish to be admired, to receive a tacit acknowledgment of one's sexual value qua man or woman. This type of acknowledgment creates the heightened interest, the excitement, the color, the personal enjoyment in human relationships with the opposite sex.
There is only one ideology that would condemn it—the ideology that opposes man's enjoyment of his life on earth and holds sex as such to be evil—the same ideology that is the source and cause of anti-obscenity censorship: religion.
For a discussion of the profound, metaphysical reasons of religion's antagonism to sex, I refer you to my article "Of Living Death" (The Objectivist, September-November 1968), which deals with the papal encyclical on contraception, "Of Human Life." Today, most people who profess to be religious, particularly in this country, do not share that condemnation of sex—but it is an ancient tradition which survives, consciously or subconsciously, even in the minds of many irreligious persons, because it is a logical consequence implicit in the basic causes and motives of any form of mysticism.
