Morality in sexual relations, when it is free from superstition, consists essentially of respect for the other person, and unwillingness to use that person solely as a means of personal gratification without regard to his or her desires. It is because prostitution sins against this principle that it would remain undesirable even if prostitutes were respected and the risk of venereal disease were eliminated.
