Anal Sex Is More Common Than Having a Twitter Account in the United States

In the current issue of Sexually Transmitted Diseases, Habel et al. examine the prevalence and correlates of oral sex and penile–anal intercourse (PAI) between male–female partners, reporting high endorsement of these behaviors in a nationally representative sample of US adolescents and adults aged 15 to 44 years. Unsurprisingly, more than 75% of women and men reported having given and received oral sex over their lifetime, with trivial proportions (6% of women and 7% of men) using a condom at their last oral sex encounter. Lifetime male–female PAI was reported by a significant minority of both women (33%) and men (38%), among whom only 21% and 30%, respectively, used a condom at last PAI.
