Same-sex polyamory

Same-sex polyamory, LGBT polyamory, queer polyamory, gay polyamory, or lesbian polyamory refers to polyamorous relationships which involve three or more partners of the same sex.

Prevalence
Polyamory is "a well-accepted part of gay subculture", although "often viewed by some therapists as problematic"; somewhere between 30% and 67% of men in male couples report being in a sexually non-monogamous relationship. According to Coleman & Rosser (1996), "although a majority of male couples are not sexually exclusive, they are in fact emotionally monogamous." Shernoff states that:


 * "One of the biggest differences between male couples and mixed sex couples is that many, but by no means all within the gay community have an easier acceptance of sexual nonexclusivity than does heterosexual society in general [....] Research confirms that nonmonogamy in and of itself does not create a problem for male couples when it has been openly negotiated."

As an alternative union
Same-sex and opposite-sex polyamory were both included as target matters of the 2006 manifesto "Beyond Same-Sex Marriage: A New Strategic Vision for All Our Families & Relationships", which sought to expand the fight for alternative forms of family unions and units beyond the more well-known struggle for same-sex marriage.

Same-sex polyamory and parenting
Same-sex polyamory may also inherit elements of issues and solutions from both LGBT parenting and polyamorous parenting.

Both accusations of polyamorous relationships and homosexual relationships have been used in child custody disputes to invalidate the "offending" party's own claim to custody or visitation rights over children.
