Those “ooh’s” and “aah’s” your woman makes whenever you’re having sex can be like music to your ears. "Faster, harder, louder," you might have even said back. Those screams and shrieks, admit it, they make you feel like the ultimate performer.
But behind those moans lies a secret. Sorry to burst your bubble (and your ego), but if you think those sounds are positive responses to all the touching and kissing, you're wrong.
According to a study published in the Archives of Sexual Behavior, women moan and groan during sex mainly for two reasons: 1) to speed up their partner’s climax, 2) to boost their partner’s self-esteem.
Yep, it’s not wholly because of your performance. Sorry.
The researchers, headed by Gayle Brewer of the University of Central Lancashire and Colin Hendrie of the University of Leeds, asked 71 sexually active women why they vocalize during sex. They found that 66 percent of the respondents moan simply to speed up their partner’s orgasm, while a whopping 87 percent said they do that to pretend they’re reaching their peak, just so you'll feel good about yourself.
