Polygamy refers to having multiple spouses in a marriage (one-to-many).
Types of polygamy[edit | edit source]

Polyamory refers to having multiple romantic/sexual partners of any sex, but not necessarily in a formal marriage (in fact such unions are not legally accepted as marriages), with potentially multiple men and women forming a sexually active union (many-to-many or one-to-many).
Polyamory is multiple loves, there may or may not be a marriage. Polygamy is multiple marriages, there may or may not be love.
Monogamy refers to a "heteronormative" (i.e. normal male-female) one-to-one union.
