Same-sex relationships involve which of the following?

Same-sex relationships are defined as romantic or sexual partnerships between individuals of the same sex. This understanding encompasses a range of relationships, including those between men or those between women, and highlights the emotional and social connections formed in such partnerships.

These relationships can encompass various dynamics and expressions of love, similar to heterosexual relationships, and can include cohabitation, marriage, or other forms of commitment, which are recognized in many places, including Canada, where same-sex marriage has been legalized.

The other options do not accurately represent the nature of same-sex relationships: relationships between individuals of different sexes do not fall under the same-sex category, financial agreements can occur in various types of relationships but do not define them, and cultural norms may influence relationships but do not specifically pertain to the definition of same-sex partnerships.
