Ladies stake their claim by faking their moan

Meg Ryan showed millions of women how to convincingly fake it in an iconic scene from "When Harry Met Sally."

Half of you ladies have faked an orgasm at least once, scientists claim. Maybe you knew the real thing just wasn’t gonna happen, so you wanted to wrap it up and go to sleep. Perhaps you didn’t want to bruise his ego.

Or maybe you thought it was a way to keep your man from straying.

At least that’s what a new study concludes.

“By having an orgasm, women are signaling to their male partner that ‘I’m selecting you,’” lead author Farnaz Kaighobadi says.

Kaighobadi, a research fellow at Columbia University, and her coauthors wanted to see whether women would be more likely to send that signal, even if they weren’t really feeling it at the moment, if they suspected their mate of infidelity.

For their study, Kaighobadi and her coauthors recruited 453 straight women who’d been in a relationship for at least six months. The young women – 22, on average – all lived in south Florida. They were asked if they thought their partner would cheat if given a chance and if they’ve done so-called “mate retention acts,” like call their man at unexpected times to see if he was really home alone watching ESPN or held his hand when other women were checking him out.

As researchers suspected, women who thought their men were more likely to be cheating louts were more likely to stake their claim – and fake an orgasm.
