Same-sex relationship

A same-sex relationship, also known as same-gender relationship is a romantic or sexual relationship between people of the same sex or gender.

Some couples in same-sex relationships have children, both biological or non-biological, such as adoptive or foster children, and are parenting them with their partner.

Same-gender or same-sex marriage refers to the institutionalized recognition of such relationships in the form of a marriage; civil unions exist in some countries where same-sex marriage does not.
