She's Not Feeling Sexy? Blame It on Guilt Some women may not realize arousal, research shows By Evann Gastaldo, Newser Staff Posted Jan 6, 2010 11:49 AM CST 30 comments Comments "Not tonight, honey. I have a headache." Or maybe it's something else... (Shutterstock) (Newser) – Not in the mood to get frisky tonight? Are you sure? A new study shows women may be turned on and not realize it—and the cause is linked to guilt. Researchers who looked at 132 studies carried out over 40 years found that some women, though showing clear physical signs of arousal, did not report feeling sexually aroused. Worse, this “may be the norm for many women,” the report says. This can be attributed, in some cases, to women’s “sex guilt” causing reluctance to admit arousal. Men, on the other hand, had no similar problem—and this is an evolutionary advantage, allowing them more chances to reproduce, the Telegraph reports, citing a study in the Archives of Sexual Behavior journal.
