An Event-Level Analysis of the Sexual Characteristics and Composition Among Adults Ages 18 to 59: Results from a National Probability Sample in the United States

Findings demonstrate that adults ages 18 to 59 engage in a diverse range of behaviors during a sexual event and that greater behavior diversity is related to ease of orgasm for both women and men. Although both men and women experience sexual difficulties related to erectile function and lubrication with age, men's orgasm is facilitated by sex with a relationship partner whereas the likelihood of women's orgasm is related to varied sexual behaviors.
