Same-sex couples are two individuals of the same gender who form a romantic and often committed relationship. These couples may choose to live together, share finances, and support each other emotionally and socially, similar to heterosexual couples. In many countries, same-sex couples have the legal right to marry and adopt children, reflecting a growing acceptance of diverse family structures. Organizations like The Human Rights Campaign advocate for equal rights and protections for same-sex couples, promoting understanding and acceptance in society.
