Same-sex relationships

People with a homosexual orientation can express their sexuality in a variety of ways, and may or may not express it in their behaviors. Many have sexual relationships predominantly with people of their own sex, though some have sexual relationships with those of the opposite sex, bisexual relationships, or none at all (celibacy). Studies have found same-sex and opposite-sex couples to be equivalent to each other in measures of satisfaction and commitment in relationships, that age and sex are more reliable than sexual orientation as a predictor of satisfaction and commitment to a relationship, and that people who are heterosexual or homosexual share comparable expectations and ideals with regard to romantic relationships.
