Sexual ethics (also referred to as sexual morality) refers to those aspects of ethics that deal with issues arising from all aspects of sexuality and human sexual behaviour. Broadly speaking, sexual ethics relates to community and personal standards relating to the conduct of interpersonal relationships, and deals with issues of consent, sexual relations before marriage and/or while married, including issues of marital fidelity and premarital and non-marital sex, issues related to sexuality, questions about how gender and power are expressed through sexual behavior, questions about how individuals relate to society, and questions about how individual behavior impacts public health concerns.
Ethical dilemmas which involve sex can often appear in situations where there is a significant power difference or where there is a pre-existing professional relationship between the participants, when there is an age difference, or where consent is partial or uncertain. Sexual ethics can also include the ethics of procreation.
