From an interview of Gore Vidal published in The Atlantic

Have you met President Clinton?

Yes – and I like Bill. My family is Southern. I’m used to Bill Clintons. The country apparently wasn’t, though. At the time of his impeachment trial, I wrote a defense of him. When he claimed, “I didn’t have sexual relations with that woman, Ms. Lewinsky,” he was totally accurate.

You believe him?

He was talking Southern. In the South, sex is when you put it in and pump away and there’s a danger of a baby. That’s “sexual relations.” Anything else is what we called in school “messing around.” And all Southern boys messed around.
