Same-sex polygamy refers to the concept of polygamous matrimonial unions between three or more people of the same sex. As of 2008, the topic has not been explored as a possible legal course for same-sex marriage, as polygamy is illegal in most Western countries (including those which offer various degrees of civil rights and liberties to LGBT citizens) while homosexuality is illegal or suppressed in most non-Western countries (including those in which polygamy, usually of the polygynous form, is legal and protected to various degrees).
