Good point. I think more appropriate to ask, how often are your needs met, in tune with each others needs, willingness to satisfy needs, by whatever means, i.e. emotionally or physically. Dysfunction implies that there is an imbalance, usually from the unwillingness of your partner to reach a mutual compromise. If you are able to come to some common ground, reaching a compromised solution, then you may fit in the neat description of "sexually compatible". All couples have times when needs go unmet, through illness, travel, work,kids, many reasons really. Either you reach a coping mechanism, give up, or look elsewhere to have those needs met, we all find a way to adapt. Happy couples discover this early. Divorced couples do not. And then there is the rest of us, suffering in SSM, hoping for some sort of solution. Keep talking and exchanging ideas, I have found it very helpful.
