Women need a good man to be happy, but good men run from a lot of modern women like vampires from garlic.
After >30 years of carriage to the same woman and based on conversations with some of my more trusted close friends have come to the conclusion that women need sex as much as men and when they are not having it regularly with the same man they have problems.
If i am traveling for work more than a night or two or she has to take our offspring somewhere for a couple days I am definitely dealing with a different person (though its clearly NOT intentional)
