you really believe there is such a thing like sex addiction ?
to me, that is just a mask for HSD.
if the lady doesn't put in effort to please her man sexually, there are many ladies out there willing to take up her role as long as the guy have attractive qualities to offer.
is a competitive world out there now, being married does not mean your love will last forever or you can be complacent about your other half if you don't understand your man's needs.
of course if you feel that you don't necessary have to please your other half, then i can say at least there is less heart break in being a single.
as a single, nothing can hurt you.
