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.

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.

The lowest condom usage rates were for men over 50 ? and the researchers said this was worrisome. Although men in that age group are more likely to be married than males in their teens and 20s, other surveys have shown 50s-and-over to be far more open to multiple sexual partners than in the past, raising the risk for disease.
