The tips will work for many people, but not all. It may be that in Michael2691's case, as appears to be my case as well, all of the steps have been performed many times. And so it isn't always effective to say, "if it didn't work, go back to step 1 and repeat".

The problem is the assumption that a sexless marriage always implies a dysfunction with either partner. Sure, the marrriage might be considered dysfunctional, but the cause may be only the mismatch. Otherwise, why is it not considered a dysfunction if two married people have agreed not to have sex? Or why is a woman living alone, successful in her career and happy with friends, but not having a relationship and no sex, not considered dysfunctional?

What have I done to seduce my wife? If it were that simple, I wouldn't be on this forum.
