An ethical relationship, in most theories of ethics that employ the term, is a basic and trustworthy relationship that one has to another human being, that cannot necessarily be characterized in terms of any abstraction other than trust and common protection of each other's body. Honesty is very often a major focus. Basics Usually studied is the relationship between the mother and child, and second most basic is between sexual partners—the focus of feminism and Queer theory respectively, in which relationships are central. Family role theory extends this to study paternalistic, maternalistic and sibling roles, and postulates that one's later relationships are formed largely in order to fill the roles one has grown to find comfortable as part of one's family environment—the family of origin thus setting pattern for the family of choice.

Thus they focus on unequal power and such matters as sexual honesty, marital commitment, child-raising, and responsibility to conduct such essential body and care matters as toilet training, weaning, forming attitudes to sexuality and to masturbation. Failures to consider consequences of teachings or examples set in these matters is disastrous, as it leads to failures of the most fundamental relationship any person has: to their own body, shame in it, pride in it, care for it, etc. Care and concern for other's bodies follows. No ethical tradition has failed to prescribe at least some rules for the conduct of such relationships. Carol Gilligan famously championed the role of relationships as central to moral reasoning, and superior as a basis for understanding human choices than any prior linguistic or meta-ethical concept. This perspective is now commonly called the ethics of care. Lawrence Kohlberg, famous for work on moral development as a part of human development, eventually joined Gilligan in starting a descriptive ethics of relationship conduct in what they
