My wife and I are in our 50's, kids have moved out, and it's only a few more years till retirement. At least it will be if my wife doesn't leave me. You see ever since our kids moved out I thought we'd be having way more sex, now that our home is open after all. But instead my wife shut down and has basically become a nun without the uniform. The mention of sex and she gets a headache, or is busy or on her period, or any other excuse. Neither of us are out of shape, she goes to the gym regularly so it can't be that. I'm a successful lawyer and make very good money, living in a nice neighborhood in NYC, so it's not a money issue. In fact, I can't think of any reason for her to act this way.
