I am just turned 50 year and my wife is of 43 year old. We married for the last 25 years and had active and enjoyable sex life till around 4 years ago. For the last four years my wife gradually lost interest in the act and for the two years I can say she won't have orgasms beyond couple of times. As I understood that this can be a harmonic imbalance, I tried to convince her to see the doctor, however she neither refuses outright nor express any interest in seeing the doctor. Before she gradually last interest in the act, she used to have a severe headache followed by attaining orgasm. I suppose this apart from normal hormonal changes are the reasons for near no libido. I have, with a great difficulty convinced her to see the doctor and able to take her to homiocare international, where in they promised to cure with use of long term homeopathy medicine usage. However I don't see any improvement during or after the treatment period of over year and three months. In fact I see that this problem is worsening. As I am active and felt deprived of the enjoyment, I tried to convince her to allow me to work on her to stimulate her. She is not comfortable if I tried various methods of foreplay including oral on her, however she is even more uncomfortable when I try various methods to stimulate. We are now hit the dead end. Meanwhile, due to lack of sexual enjoyment, I am restless and unable to have a good night sleep and I feel slowly effecting my overall health despite I being physically very active. I have no clue as to how to go about it. Can you please suggest how we can get back to normal situation. Every passing day, I am becoming more and more desperate and feel the need more and more. In fact she allows me to penetrate and relieve my self, despite this I am not satisfied as such I don't enjoy this one side act and looking her to be active part of this. I am feeling please help. I understand that there is a medicine which can be taken before the starting of the act to avoid headache. Please suggest.
