I think the word "covet" is key to the idea Dr. Vaillancourt is trying to express. "To covet" is a vastly different idea than "to value", "to desire" or "to want" as it conveys an unsavory and darker air. I would say that sex is a drive that all sexually reproductive organisms share, but I personally think that covetousness is outside of the capabilities of something like ants or weasels.

That said, I don't particularly agree that Dr. Vaillancourt's statement rings true for men in general. Naturally, men (like women) desire sex and desire sex with desirable partners (duh) but her statement seems overly simplified and a bit flip, especially when she follows that statement with ideas about power dynamics. Men use sex to gain power too, though generally in a different way than women do, because men and women have different sexual roles within their societies and often different avenues to power.

Edit: I just realized that I posted this article a while ago, except the link I posted ends a little differently. All that damn junk at the end . . .
