Women who fake their orgasms more often are more likely to cheat, according to a new study

Well that's one way to introduce some awkwardness into your pillow talk.

Women who fake their orgasms more often are more likely to cheat, according to a new study

Women who fake orgasms in bed might be more likely to cheat—or so goes the theory, according to a new study out of the University of Missouri and Carnegie Mellon published in the academic journal Archives of Sexual Behavior.

But hang on: Let's go over a few important points. First, even if your girlfriend is faking orgasms in bed, there's a pretty good chance you don't realize it. And even if she is faking it, she might just be doing it because she doesn't want to hurt your feelings—just because she's getting theatrical between the sheets doesn't mean she's getting down with another man.

In the study, researchers tried to test the "female fidelity" theory, which suggests that the female orgasm "signals a woman's sexual satisfaction, and therefore her likelihood of future fidelity to a partner." They surveyed 138 women and 121 men currently in a sexual relationship, and asked a variety of questions about the frequency of their orgasms as well as infidelity.  That's notable for two reasons: It's a relatively small study size, and questionnaires aren't necessarily the most reliable method of gathering data, as psychological studies go.

When the researchers analyzed the results, they found that the "female fidelity" theory was pretty much a non-starter. "Orgasm was not associated with female sexual fidelity, nor was orgasm associated with male perceptions of partner sexual fidelity," the authors wrote.

They did find, however, that "faked orgasm was associated with female sexual infidelity and lower male relationship satisfaction." In plain English: Women who faked orgasms were likely to be unfaithful, and to have partners who weren't as happy with their relationships.

Again: It's not an ironclad sign. And before you blame your partner, maybe you should check up on your own prowess first, champ: Check out the best sex positions to satisfy her, the 10 moves she's begging you to make during foreplay, and what women wish you knew about getting them off. (After all, straight women don't orgasm as often as you'd think.)

But if you're still suspicious, read up on these ways to tell if she's cheating. Then have an honest conversation with her. You'll either find out if your relationship is doomed, in need of serious repair. Or you could find out that you're simply sub-par in bed.

Hopefully none of those things.
