Over the last three decades the sexual morality of many Western societies has changed beyond recognition. Most of the prohibitions which made up the traditional, extremely restrictive outlook on sex that reigned supreme until the fifties–the prohibitions of masturbation, pre-marital and extra-marital sex, promiscuity, homosexuality–are no longer seen as very serious or stringent or, indeed, as binding at all. But one or two traditional prohibitions are still with us. The moral ban on prostitution, in particular, does not seem to have been repealed or radically mitigated. To be sure, some of the old arguments against prostitution are hardly ever brought up these days; but then, several new ones are quite popular, at least in certain circles. Prostitution is no longer seen as the most extreme moral depravity a woman is capable of; but the view that it is at least seriously morally flawed, if not repugnant and intolerable, is still widely held. In this paper I want to look into some of the main arguments in support of this view and try to show that none of them is convincing.
