When we got married 14 years ago, she was great in the sex dept -- sometimes 3 times in one day! But over the years with some health issues, she lost some interest in sex. I treat her like a queen and tell her that I love her every day (because I really do). I do not use porn in front of her or tell her that I am unsatisfied sexually -- this would only make a bad situation worse. I have never suggested to her that I wanted to swing but a few years ago I asked one of those "what if" questions to test the water. So that is how I know that she has no interest in swinging. She has told me that I completely satisfy all her needs but she is unwilling and in some cases unable to satisfy me.
I have planned a romantic vacation in Las Vegas on the Oct 9th. I buy her gifts and show her that she is very important to me. She knows that she is loved and has told me multiple times that she is sorry for her lack of interest in sex. This might just be a situation without real solution.
