Women's social desirability scores were not related to their reports of thoughts about sleep, however, perhaps because there are no stereotypes about women and sleep the way there are about women and sex they aren't supposed to think about it as much as men and women and food they aren't supposed to eat it as much as men. It was immediately apparent that both men and women were quite variable in the frequency with which they engaged in sexual thoughts. These findings paint a rather different picture of men than does the urban legend of thinking about sex many times per minute. The typical men in this sample were thinking about sex once or twice an hour, and statistically no more and no less than they were thinking about eating or sleeping. Be sure to read the following responses to this post by our bloggers: However, there is quite a bit of research to suggest that they are more similar than different, even among college students, who are likely at an age at which gender differences in sexuality are maximized. Another scale that we administered to the participants measured their degree of comfort with sexuality erotophilia. We also don't know if all of our participants followed the instructions and really clicked every time they had the sort of thought that they were supposed to track. That wasn't really true, and when the study was over, we told them that wasn't true, but we wanted to do what we could to make sure that the participants did what they were supposed to be doing. The tally counts reported by the men ranged from 1 to Although on average, the men in our study did report more thoughts about sex than did the women, many of the women reported more sexual thoughts than many of the men. In addition, there are other types of need-based thoughts that people have in the course of the day, and we thought it would be interesting to use the frequency of those thoughts as a comparison for the frequency of sexual thoughts. A couple of years ago, I was discussing the lack of good research in this area with my Psychology of Human Sexuality students, and indicated that this would be an interesting area in which to do research, if any of them were interested. This, of course, is not what we found after the participants actually tracked their thoughts, illustrating the difference between the two methodologies. We never intended our research to be used to draw conclusions about the entire population. There is some evidence that at least some women were reluctant to report certain types of thoughts.
