No that's not a possible explanation. Look at the charts for women. 80% of women have just a single partner in a given year and 60% have regular sex every week.

No that's not a possible explanation. Look at the charts for women. 80% of women have just a single partner in a given year and 60% have regular sex every week. This hasn't changed over time. For a hidden exponential right tail to explain this, you would need to believe that women are overwhelmingly switching into weekly, committed relationships with a small number of men and no others. You would also need to believe that these alpha males are bedding all of those women weekly. That doesn't make logistical sense, and isn't the story people are trying to tell either (that a small number of men are doing a different woman every other day and keeping them satisfied and off the market). These alpha male type men may exist, but they're a drop in the bucket compared to well documented factors like worsening economic conditions.
