Guilt and jealousy

While most people do not feel guilt or disgust about their sexual thoughts or fantasies, a substantial number do. In general, men and women are equally represented in samples of those who felt guilt about their fantasies. The most notable exception was found in a 1991 study that showed that women felt more guilt and disgust about their first sexual fantasies. In women, greater guilt about sex was associated with less frequent and less varied sexual fantasies, and in men, it was associated with less sexual arousal during fantasies. Women also reported more intense guilt than men; both sexes reported greater guilt if their arousal and orgasm depended on a fantasy.
