NEW YORK (AP) - The male-female orgasm gap. The sex lives of 14-year-olds. An intriguing breakdown of condom usage rates, by age and ethnicity, with teens emerging as more safe-sex-conscious than boomers.
That's just a tiny sampling of the data being unveiled Monday in what the researchers say is the largest, most comprehensive national survey of Americans' sexual behavior since 1994.
Filling 130 pages of a special issue of the Journal of Sexual Medicine, the study offers detailed findings on how often Americans have sex, with whom, and how they respond. In all, 5,865 people, ranging in age from 14 to 94, participated in the survey.
The lead researchers, from Indiana University's Center for Sexual Health Promotion, said the study fills a void that has grown since the last comparable endeavor - the National Health and Social Life Survey - was published 16 years ago. Major changes since then include the spread of sexually transmitted diseases, the types of sex education available to young people, the advent of same-sex marriage, and the emergence of the Internet as a tool for social interaction.
Dr. Dennis Fortenberry, a pediatrics professor who was lead author of the study's section about teen sex, said the overall findings of such a huge survey should provide reassurance to Americans who are curious about how their sex lives compare with others.
"Unless, like al-Qaida, you feel there's something abnormal about the American people, what these data say is, 'This is normal - everything in there is normal."'
The researchers said they were struck by the variety of ways in which the subjects engaged in sex - 41 different combinations of sexual acts were tallied, encompassing vaginal and anal intercourse, oral sex, and partnered masturbation.
Men are more likely to experience orgasm when vaginal intercourse is involved, while women are more likely to reach orgasm when they engage in variety of acts, including oral sex, said researcher Debra Herbenick, lead author of the section about women's sex lives.
She noted there was a gap in perceptions - 85 percent of the men said their latest sexual partner had an orgasm, while only 64 percent of the women reported having an orgasm in their most recent sexual event.
One-third of women experienced genital pain during their most recent sex, compared to 5 percent of men, said Herbenick, citing this as an area warranting further study.
