Quote of the day—Dr. Justin J Lehmiller

Nearly half of men and one-third of women would, ideally, like to be practicing some form of non-monogamy. However, just 8% of men and 7% of women said they wanted to be in a completely open relationship. This means that most of the people who are into non-monogamy want there to be at least some rules or restrictions in place.

Would Your Ideal Relationship Be Monogamous Or Open? 1,000 Americans Weigh In
[Isn’t that interesting?

Anonymous Conservative would say it’s validation of r/K theory in a nearly free resource environment.

The authors of Sex at Dawn: How We Mate, Why We Stray, and What It Means for Modern Relationships would probably say the only surprise is that the percentage is so low.

Here is where it gets even more interesting:


Behavior doesn’t change much with age but openness with their partners does.

    • Well, for a brief refractory period, Joe’s Cure for Everything does cure this, too.

  1. “Behavior doesn’t change much with age but openness with their partners does.”

    It seems to me that chart shows differences in behavior or attitudes between demographic cohorts rather than changes with age. The concept of an open relationship was all but unknown when those currently over 65 were young enough for the question to have much meaning.

    As a general rule the numbers would increase with age.

    • 24% total over the course of a lifetime for those over 65, less than half a percent per year.

      28% total over approximately 35 years for those aged 45-64, still less than 1% per year.

      34% total over approximately 20 years for those aged 30-44, more than 1.5% per year.

      38% total over approximately five years for those aged 18-29, over 7% per year.

      That seems like a huge cultural shift to me, even if the time distribution of non-monogamous behavior for a given cohort is non-homogeneous, the change from 24% to 38% is quite large.

  3. I’d like to see the breakdown of men Vs Women for each age group…

    And I should point out that the study assumes no one was lying about it…
