Quoting lostlove:just because the research shows that we are on a basic animalistic level wired for such behaviour doesn't exuse it.
What the research does for me is to absolve me of some of the guilt. Yes, I need to listen more and be eager to satisfy my wife's non-sexual needs. Yes, I sometimes poison her desire by getting frustrated and unhappy. But I also know that there are thoughtless cretins whose wives are crawling all over them for some physical intimacy. Why, why, why?? It's not that I'm a jerk, or unattractive, or a bad lover. There is a genetic and biological basis for sexual desire that we have little control over. And trying to apply logic and morals to it is almost hopeless.
