Of course this is sometimes true... but sometimes it doesn't work. That’s what I pointed out. Many men try to be a better partner, but it often doesn't work anyways, sex-wise (so many comments on this kind of article confirm this).

As you state, monogamy tend to "kill" women's sex drive. One can be a better partner, or doing home stuff all the time... but it's still monogamy.

The ironic thing is, it's women who mostly look for relationship stability: and yet it's exactly that making them bored, less sexually open and warm. It's a conundrum.
