Yes, but is it sex?

It's all a word game ...

President Bill Clinton said oral sex wasn't sex. South Carolina Gov. Mark Sanford says in his latest revelation that he "crossed lines" with women other than his wife and Argentine mistress, but "didn't cross the sex line." He wouldn't say what that meant.

If those distinctions have you confused, you aren't alone. Neither are Clinton and Sanford.

Americans just aren't explicit when they talk about having "had sex."

"Sex is a word and nobody is really in charge of that term," said Kinsey Institute scientist Erick Janssen. "In a way, our thinking of sex and definitions of sex is more complex than they were in the past."
