Researchers at Indiana University have just released the very large and very comprehensive National Survey of Sexual Health and Behavior (NSSHB). With responses from 5,865 people ages 14 to 94, the survey asked about frequency of sex, types of partners, paying for sex and even how much pleasure or pain they got from sexual activity. The always-interesting Cory Silverberg at About:Sexuality spent the weekend with the report (bless his heart) is doing several posts on this gigantic study, the first of which includes some of the highlights (and the entire thread is here.) His posts explore both the good and questionable data, and he makes the point that some of this information has been known to health educators for a while now, but not to the general public.
Unfortunately, he hasn't done anything on age of first sexual experience or the number of non-sexually-active respondents, but that may come in later posts or papers. You can click here for a chart on different sexual activities by age. If you want to do your own research, you can download the first nine papers here.
Here are some of Cory's and our highlights:
Not all teenagers are the same. By collecting data from adolescents age 14 and up, the survey foregrounds the transition moment between the ages of 16-17 and 18-19, where teenagers show a huge leap in both kind and frequency of sexual activities. To offer one example, twice as many women between 18-19 report having had oral sex, vaginal intercourse, and anal sex as women who are 16-17. The data also let us see that condom rates also drop during this transition, in some groups by as much as 50% between the ages of 14-17 and 18-24.
53% of participants were with a romantic partner, 24% had a casual sex partner, and 9% had sex with a "new acquaintance"
Across age groups 6% of men and 30% of women reported some pain at their last sexual encounter. These percentages are striking both in terms of the sheer number of people they represent who are experiencing pain during sex, and the significant (but not surprising) gender discrepancy.
Overall 91% of men and 64% of women report having an orgasm at last sexual encounter. At the same time, 85% of men and 92% of women believed their partner had an orgasm the last time they had sex. These data can't be directly compared given the small group of people who have same sex partners, but the discrepancy, particular among men, is notable. Clearly more men think their partners are having orgasms than they are.
