Sexual behavior changes over time, and the trajectory of change may vary between men and women.
Young women may have difficulty navigating cultural attitudes about sexual behavior and promiscuity as they first explore their sexuality, but age brings confidence and greater skill at communicating their needs and desires. Young men often have concerns about performance, penis size, or premature ejaculation. Anxiety is a threat to performance for either men or women.
Couples tend to report that their sex life is most robust in their 30s and 40s, but sex is often most deeply rewarding for older partners. People can enjoy satisfying sex throughout the lifespan if they make adjustments for the many changes that time brings, such as relying less on penile penetration and more on massage, whole-body touching, and oral sex.
