Thundarr, to me the Kinsey level of scientifical data is compromised because he manoeuvred is subjects to obtain the data we was looking for. My friend who is a psychiatrist and many of his fellow colleagues have the same view about Kinsey.
Now, as for Monogamy being dead. It is as dead, or alive, as it was centuries ago. In past centuries people did not marry for romantic love so, escapades, especially from the man, were seen as natural.
People believe in partners for live (think even MClers do) yet, believing one thing and sticking to it are two different things. Also, partner for life does not automatically equal being always faithful to that partner or to not have another sexual partner while you are married. You know that Thundarr, you’ve had your little affair all those years ago.
I think humans are monogamous for the most part but many humans have, once, or twice, strayed. If humans were not mostly monogamous we had not survived the pre-historic times. The conditions/society of those times did not allow for such kind of things.
However if you do an anthropologic research you will find that the uses and ways of people differ in time and geography so it is not possible to say that humans are 100% monogamous or that they are not monogamous at all.
LBS may believe in a partner for live but certainly they no longer believe they were always going to be the only sexual partner of their spouse. In the future they may again be, but there was a time when their spouse had someone else. Sometimes for years on end. Anyway, like Stayed I think there is more then one person for each of us. That is different from infidelity, of course.
