Markets in sexual services can serve legitimate needs  While many societies have attempted to restrict sex to marriage, few (if any) have succeeded. In contemporary, secular liberal societies, adults are no longer punished for pursuing sex outside of marriage. Many adults find non-marital sex satisfying, healthy, and fulfilling, whether it occurs in the context of an ongoing romantic relationship, a casual friendship, or a market exchange. While many people will never seek the services of a sex worker, those who do are often seeking sensual comfort, companionship, entertainment, and fantasy fulfilment. While the latter goods are often obtainable in non-market relationships, some people prefer the convenience and efficiency of market mechanisms for securing these goods.  In a liberal society, individuals are free to pursue their own vision of happiness, as long as they respect the moral and civil rights of others. Markets that provide sexual services enable some individuals to secure goods essential to their happiness. Those who provide services to these individuals can do so in a manner that respects their rights and dignity, if the markets are legal and well regulated.
