People who engage in market sexual relationships and other forms of casual sex can treat their partners with dignity and respect. This involves respecting the boundaries that sexual partners communicate to each other, regarding what parts of their lives and themselves they are willing to share. With different sexual partners we open up in different ways, and people who engage in casual, market sexual relationships might draw different emotional and sexual boundaries in these relationships than in others. While casual sexual relationships are unlikely to involve commitments of fidelity and exclusivity, they are compatible with the decent and respectful treatment of others if persons in these relationships respect their partners’ rights to privacy, autonomy, and other basic interests.
