Erotic or sexual fantasy is completely normal, yet, many people are ashamed to admit they indulge in them. Especially female fantasies. A survey conducted by The New York Times revealed that 48% versus 46% of respondents believed that fantasizing about someone else during sex was equivalent of being unfaithful. However, other studies have found that the number one fantasy people have during sex is fantasizing about someone else. These fantasies often leave individuals feeling as though they have committed mental or moral infidelity. Nonetheless, fantasizing about sex, including fantasizing about someone else while having sex with a partner is not only normal, it is also common.
