Sexuality changes across adulthood. In early adulthood, people establish their sexual orientation and identity, develop intimate relationships, and make choices around fertility.

In late adulthood, biological changes can impact sexuality but emotional and relational aspects remain important, and many still find sexual activity and satisfaction regardless of age.
