A "birds and the bees" talk with your kids isn't complete without a discussion of oral sex, according to a new study that found a connection between oral sex and old-fashioned intercourse.

The three-year survey found that teens who had oral sex by the end of ninth grade were at the highest risk of having sexual intercourse during high school. These teens had a 25-percent chance of having intercourse by the end of ninth grade and a 50-percent chance by the end of 11th grade.

Meanwhile, teenagers who did not have oral sex until the end of 11th grade had only a 16-percent chance of having intercourse by the end of that school year.

The survey also found that most sexually active teenagers will start having oral sex and intercourse within the same six-month period.

Health care providers, parents and educators should directly address oral sex and its risks with teens, according to study researcher Bonnie Halpern-Felsher, a professor of pediatrics at University of California, San Francisco.
