Kara and Pam were discussing their sex lives.
Kara lamented, “Mine’s OK. We get it on about once a week, but it’s no big adventure. How’s yours?”
“It’s been great ever since we started doing S&M,” blurted Pam.
Kara was surprised. “Really, Pam? I never would have guessed that you were into that sort of thing.”
“Oh, sure,” said Pam, “He snores while I masturbate.”
