I realize that many well-meaning parents will disagree with me, but spanking kids is gross. There are a lot of reasons why—it’s counterproductive and ineffective, for starters—but there’s another reason that nobody talks about. Butts are sexual. That’s why the area is one of the few “private” parts that, along with breasts and genitals, we feel the need to cover with a swimsuit. If a parent saw a teacher patting a child’s shoulder, it’d be no big deal. But if a parent saw a teacher patting a child’s butt, she would (rightly) be very alarmed.

So I have a question: If it’s “somewhat pedophilic” when my adult husband consensually spanks me in a simulated “punishment,” what should we call it when parents do the same physical thing to actual children in an actual punishment?

Spanking is a sex act. It has been for a very long time—probably even longer than it’s been a parenting choice. A fresco at the Etruscan Tomb of the Whipping, which dates back to approximately 490 B.C., depicts an erotic spanking. In Francum, a 1599 epigram by John Davies, includes one of the most explicit descriptions of sexual masochism in Renaissance poetry. In Victorian England—well, there are way too many examples to list them all, so suffice it to say that spanking was a constant focus of Victorian erotica.
