Reader SFG suggested that I examine the claim that smart people are more likely to have anal sex because they are kinkier. Education will have to serve as a proxy measure. Here are the results for married whites from the National Couples Survey data (N = 903):
Percent having anal sex in past four weeks
No degree 28.3*
High school 10.4
* p < .05, two-tailed test, compared with BA.
Just the opposite. Anal is prolish behavior. Educated women don't go for that.
