I probably express contempt because the problem is so freaking OBVIOUS, and yet my wife makes absolutely no effort to correct the problem.
Has your wife expressed that she thinks there is a problem with the marriage?
And if she thinks there is a problem, maybe she thinks it's so freaking OBVIOUS and that YOU make absolutely no effort to correct the problem.
What I don't understand with all of this is why you aren't willing to try ANYTHING. If you are so sure you want to be a passionate lover to your wife, I would think you would be willing to try anything no matter how unusual or risky. Since you've stated you plan on staying in the marriage at least 7 more years, why wouldn't you give some suggestions a try??
