Virginity rare, drug use common in adults: study

By Maggie Fox, Health and Science Editor

WASHINGTON (Reuters) - Just 4 percent of U.S. adults are virgins but a fifth have tried hard drugs like cocaine and crack, a new study shows.

What most alarms researchers is how young they start.

"We still have a public health problem in that we still see a lot of adults reporting their sexual debut at a pretty young age," said Dr. Kathryn Porter of the National Center for Health Statistics, who led the survey of more than 6,000 people.

"That is an area of concern because risky sexual behaviors can result in sexually transmitted diseases and unintended pregnancies," she said in a telephone interview.

Ninety-six percent of U.S. adults aged between 20 and 59 have engaged in some kind of sex, including oral and anal sex, according to the study published on Friday.

The researchers believe they have one of the most honest assessments yet of sexual behavior and drug use because they used a new method to do the survey, which is available on the Internet here

"They answered this in complete privacy," Porter said.

"They have a headset on, they touch a computer screen. This is the first time we just looked at statistics for sexual behavior and drug use alone."
