Unfortunately, some women love a man's tool, and others really have little interest in it. Only the ones that LOVE that tool will actually have successful marriages. I have read the book about what men want women to know by B. DeAngilis, and it basically is the instruction manual for women to use. If your wife follows the manual, she will have a very successful marriage. I could give that book to my wife and say, read it and live it and we will have an incredible marriage. The only problem is that she has no hope of ever being able to follow the instructions as she can not possibly change enough to do those things.

It really is quite simple, you just have to love sex and desire sex with your spouse. Unfortunately, almost half of all women are NOT really capable of being like this, and we are the unfortuante guys that married one of these women.
