In my opinion, the original post person meant, would you pick being treated well in your relationship, a loving monogamous one, even through the sex was not that great for whatever reason... as compared to being with someone who you have mind blowing sex with but they are just not good "be with you" companions... other than that. I stayed in a relationship for a year on and off even though the guy would promise times together and then just disappear. Sex is addictive and can really hook you so that you ignore your "good sense". Of course we all want both, but how often do we get that?
