"To allow one's person for profit to be used by another for the satisfaction of sexual desire, to make oneself an Object of demand, is to dispose over oneself as over a thing and to make of oneself a thing on which another satisfies his appetite, just as he satisfies his hunger upon a steak.
The desire which a man has for a woman is not directed towards her because she is a human being, but because she is a woman; that she is a human being is of no concern to the man; only her sex is the object of his desires." - Immanuel Kant
