James,
Women are always wondering, "Am I lovable?" ... Men are always wondering, "Am I enough?" Women want to feel loved for who they are on the inside. Whereas men want to be appreciated for what they do on the outside. So, for you, James, if your wife is being very appreciative of things you do and showing you respect, you are more likely to feel happy in your relationship with her. But it's different for your wife. She needs to know you love her for who she is on the inside. That is the key to unlocking her desire for sex. If she feels loved by you, she will likely be more interested in sex. I would be happy to speak with you more on this and help you crack the code.
