question: My husband and I are in our late 60s.  Up until two years ago we had a reasonably healthy sex life but even then my husband had difficulty keeping an erection.  His depression mood swings have increased over the last two years, hes become disinterested in intimacy, he lacks drive and is always tired.  He refuses to take any natural supplements to improve the situation.  He was also diagnosed with Type 2 diabetes which he has managed to reverse with cutting sugar out of his diet altogether.  We cant go on living like this.
