Gen Z may not be having less sex, just different ways of expressing intimacy and desire.

Studies often define sex narrowly, missing diverse sexual behaviors and online experiences.

In a 2021 article published in Socius: Sociological Research for a Dynamic World, sociologist Jennifer M. Silva argued that the transition to adulthood has become prolonged and individualized, with many 20-somethings spending more time pursuing higher education, establishing financial security, and reaching traditional adult milestones later than previous generations. As a result, long-term committed relationships and marriage are often postponed until........
