A new study published in the June issue of Human Nature finds that women have more negative feelings after a one-night stand than men. Researchers feel that this is indicative of the failure of the "free love" movement, since women are not enjoying the casual sex they are having. According to the survey, 80% of men had overall positive feelings about the experience compared to 54% of women. But are the women enjoying the sex itself? After all, the study seems to be based more on emotions than actual physical encounters (the predominant "negative feeling" these women had were that of being "used," and the women who were interviewed for the study at the Durham University in the UK said they only embark on one-night stands if they think it will lead to a full-blown relationship, and feel "ashamed" when it doesn't).
