I quite enjoyed your post (though you might want to fix the link, it has a comma hanging off the end.)

You point out Weiss' assertion that women do not share interest in sex or diversity of partners. I agree that it's largely unfounded, and could be explained more easily by Weiss' obvious narcassism. I mean, after all, if women are truly as sexless and monogamous as he claims, he must be a stallion, to attract so many lovers. He is, in essense, claiming that monogamous women are so turned on by him they flee from their one-partner ways (unless there really are that many single, aka unmarried AND undating, women in the area) and momentarily enflame their sexless drives.

I also strongly agree that there is an undercurrent of ownership, which ties in with the narcassism. If Weiss were truly wired for multiple partners, that should also imply that he doesn't mind HIS partner having multiple partners... after all, it is the most natural thing in the world. But he abandons multiple partners after he realizes his wife would take part in the festivities, as well. Does this not suggest emotional narcassism... not necessarily the need for multiple SEXUAL partners, but the need for singular women to love only HIM. If anything, it's a twisted form of monogamy... monogamy for the women, polygamy for the man.
