Markets in sexual services undermine the values of commitment and loyalty  Sexual relationships involve crossing ordinary social boundaries that exist between people, and exposing aspects of ourselves that normally remain private. This aspect of sexual relationships renders the parties vulnerable emotionally and socially, and therefore sexual partners often extract commitments from each other of sexual fidelity and exclusivity. These commitments allow people to engage in sexual relationships while treating each other with decency and respect.  Markets are public and involve exchanges among strangers. In markets, goods are exchanged with the highest bidders and not with those to whom we are committed and loyal. For this reason, markets in sex undermine the ideals of sexual commitment, loyalty, or exclusivity, which makes decent and respectful sexual relationships possible. Markets are for exchanging shoes and cars, or services that we can separate from ourselves without leaving us emotionally and socially vulnerable or exposed. Sexual relationships require commitments of fidelity and exclusivity so we don’t lose part of ourselves in the exchange.
