the practice of one woman having several husbands is called
Polyandry Polyandry (/ˈpɒliˌændri, ˌpɒliˈæn-/; from Greek: πολυ- poly-, "many" and ἀνήρ anēr, "man") is a form of polygamy in which a woman takes two or more husbands at the same time. Polyandry is contrasted with polygyny, involving one male and two or more females. If a marriage involves a plural number of "husbands and wives" participants of each gender, then it can be called polyamory,[1] group or conjoint marriage.[2] In its broadest use, polyandry refers to sexual relations with multiple males within or without marriage.
