Late sexual transition: Achievement of developmental tasks and well-being in emerging adulthood

According to the social clock and statistical norms, a transition into sexual activity after age 18 years is considered late. This longitudinal study examines whether late sexual transition is related to delays in the achievement of developmental tasks and lower psychological well-being in emerging adulthood for heterosexual individuals. A sample of 300 participants (61.3% women) was assessed annually from age 15 to 22 years and again at age 25, of which 43 reported sexual intercourse at age 19 or older or remained virgins in emerging adulthood. Results indicate that late sexual transition, particularly for men, is prospectively associated with still being at school, working fewer hours per week, being single and having no kids at age 25. It is also positively associated with depression and anxiety symptoms, interpersonal sensitivity, hostility, lower self-esteem, and lower happiness. This study enriches the understanding of slower developmental trajectories and the associations between late sexual transition and subsequent trajectories in emerging adulthood.
