Duogamous

Duogamous refers to a multisexual (most commonly bisexual) person who is in a polyamorous relationship with two exclusive partners. These two partners have dissimilar or opposing genders, most commonly one of each binary gender. The other two people may or may not be in a relationship with each other as well.

History
The word duogamous is mentioned in the Bisexual Manifesto in 1990. Because of identity elitism, bisexuality is commonly erased by biphobes for not practicing duogamy, as if they were not truly bisexuals.
