The U.S. Government’s Centers for Disease Control and Prevention (CDC) reports that about 40% of heterosexual Americans aged 15 to 44 have or have had anal sex with a member of the opposite sex.
iO9 breaks it down:
According to the National Survey of Family Growth, which surveyed thousands of people between the ages of 15 and 44 in 2006-2008, anal sex is really popular with heterosexuals. 44 percent of straight men report having anal sex at least once in their lives, and 36 percent of straight women do too. Though more straight men than women were enjoying anal sex, women were enjoying gay sex more. Twice as many women (12%) reported having homosexual sex at least once in their lifetimes compared with men (5.8%).
Given that the study was done from 2006-2008, it’s not unlikely to posit that the rates may actually now be slightly higher.
Wonder what Rick Santorum would say?
