Condom becomes norm for sexually active teenagers, study says

A wide-ranging study of Americans' sexual behavior, based on the largest nationally representative survey since 1992, finds that condom use is becoming the norm for sexually active teenagers.

Indeed, they are more responsible than adults about using condoms, the researchers report in a study coming out on Monday. A vast majority of sexually active 14- to 17-year-olds - 80 percent of boys and 69 percent of girls - said they had used a condom the last time they had intercourse, compared with well under half of adults involved in casual liaisons, New York Times reports.

"We found an enormous diversity in the sexual repertoires of U.S. adults," said Debra Herbenick, PhD, of Indiana University in Bloomington. "Adult men and women rarely engage in just one sex act when they have sex."

Indeed, the survey found 41 different combinations of sex acts reported by nearly 6,000 participants, Herbenick and colleagues at Indiana University reported in a supplement to the Journal of Sexual Medicine, MedPage Today informs.
