 New Natural Law is a version of any type of view that limits the morality of sexual acts to specific domains. In addition to marriage, love is another such domain. A view confining sex to love need not insist also on marriage, on only two love partners, or that they be of different sex/gender. It requires only the presence of love. Other versions require only affection or a mutually respectful relationship (Hampton 1999; Nussbaum 1995). On such views, consensual casual sex between two strangers is impermissible.
