Has your sex life always been like this or has it changed over time? If yes, have you also changed over time? Do you still give her the same level of attention, affection, romance and quality time as you did before? Do you help around the house etc? Have you asked her what you can do to help improve her sex drive? Is she willing to try a natural supplemt to increase her drive? Does she masturbate without you? If yes would she consider stopping and saving it for you? You need to communicate, think of possible solutions and look at WHY she may have gone off sex. If shes not willing to work with you to make improvements or changes then youll have to decide whether you want to stay or go. It takes two to make a marriage work, compromise and give and take. Explain that to her.
