More on CDC Sexual Behavior Survey

The report can be downloaded at the CDC website.. The data tables, rather than the "highlights" are far down on the 56 page document.

The numbers for teens are skewed by lumping 18 and 19 year olds in with teens 15 to 17 years old. However, the numbers for the younger ages are disturbing, with over 33% of 15 year old girls and 45% of males reporting sexual activity of any kind. (Tables 3, 4) There's a stronger correlation between vaginal sex and "any" sex in the girls than in the boys. (In old fashioned terms, the girls are more likely to have "gone all the way" if they've had any sexual experience at all.)

The numbers for monogamy within marriage are encouraging, with 91% of married men and 93% of married women reporting one partner in the last year. (Tables 1, 2) The numbers decrease for those cohabiting.
