Incest Taboo

An incest taboo is any cultural rule or norm that prohibits sexual relations between certain members of the same family, mainly between individuals related by blood. All known human cultures have norms that exclude certain close relatives from those considered suitable or permissible sexual or marriage partners, making such relationships taboo, though different norms exist among cultures as to which blood relations are permissible as sexual partners and which are not; sexual relations between related persons that are subject to the taboo are called incestuous relationships.
