One of the most quoted documents on adolescent sexuality was published in 1996 by Mark Schuster, a pediatrician at the University of California at Los Angeles and an investigator with RAND, a non-profit research institution. Schuster collected data from 2,026 Los Angeles teens in grades 9 through 12. Statistics are negligible, because the major national surveys on teen sexual activity don't ask about oral sex and most don't question the youngest teens. We are just not picking up on this sexual activity by our younger kids. John Santelli has analyzed four major national studies of teen sexual behavior.
None asks directly about oral sex.
Santelli works for the Centers for Disease Control and Prevention, which does one of the reports, the Youth Risk Behavior Survey. In fact, it is quite close to impossible, says Charles E. Irwin Jr., professor of pediatrics and director of the division of adolescent medicine, University of California at San Francisco. But he also believes their sexual activity may have actually decreased in the past 10 years, as teen pregnancy and teen birth rates have declined. Dr. Drew Pinsky. Others who talk to teens daily disagree.
