I can't speak for all guys, but it's not so important to for me that the sax is "good" but that it's there. Most of the guys I know (me included, sadly) have stayed in a relationship for way too long just because there was still a sex life (even if it does feel like it's on life-support).
For a relationship, I believe it is very important to have "good sex" as it seems to be an indicator to how well the relationship is going / if it might end.
Let me clarify though that my definition of "good sex" doesn't necessarily mean everyone has earth shaking orgasms (or even an orgasm at all), but that everyone enjoyed it, and each other's company such that in the end no one is left feeling unsatisfied or inadequate by any means.
