fuzzy math

I've been thinking about this article from last week's New York Times, all about how the statistic that men have more sexual partners than women is not mathematically possible.

What I have been thinking is that mathematics professors, who are notorious for never having sex, should not try to correct statistics that people know, intuitively and empirically, to be true. Because the statistics that these professors dispute are stated as medians, whereas the professors put forth corrections as averages. All it takes is one flooze in a population of prudes to create a situation where men and women average the same amount of partners but actually have very different sexual behaviors.

Take as an example Mathland, a population of exactly ten men and ten women, all perfectly heterosexual. Each man pairs with one woman, so M1 + W1, M2 + W2, M3 + W3, etc. Then it turns out that W10 has a clitoris at the back of her throat, and she is insatiably hungry, so one by one M1 through M10 accompany her down the sneeze guard at the buffet. M1 through M10 now each have had 2 partners; W1 through W9 all have 1 partner each; W10 has 10. The average amount of sexual partners that the Mathland men have had is two, and for the women the average is the same. But if you look at the medians, the men have had twice as many partners as the women.

Am I missing something here? Isn't this simple maff?


Also, these statistics totally don't take into account the fact that men have sex with each other all the time, in secret, scared of the implications, and then pretend like those partners have been girls. I rest my case.
