The incidence of oral sex among adolescents has dropped between 2002 and 2010, as has vaginal intercourse within the same age group. Still, two-thirds of young Americans age 15 to 24 have engaged in oral sex, according to the Centers for Disease Control and Prevention.
About one-quarter of young people try oral sex before they engage in intercourse. Based on National Survey of Family Growth data from 2006–2008, 45% of females and 48% of males aged 15–19 years had oral sex with members of the opposite sex, and among 20–24 year-olds, these percentages were about 81% of females and 80% of males.
The percentage of female and male teenagers who ever had sexual intercourse declined from 51% in 1988 to 43% in 2006–2010. Significant increases in condom use at first vaginal intercourse occurred for both female and male teens.
