Men and women often walk out of the bedroom with completely different ideas about what just occurred, recent research showed. The recently released National Survey of Sexual Health and Behavior found that men overestimate whether their partner has had an orgasm and underestimate their pain.

In the survey, 64 percent of women reported having an orgasm last time at bat, but 85 percent of men said their female partners had one. Also, about 30 percent of women reported that sex was painful and, presumably, men are unaware of that too, or else, being the gallant gentlemen we are, we’d stop and snuggle. (Hey, it could happen.)
