My husband has let himself go physically, gained 40lbs, and now only 1 or 2 sexual positions are possible.Also, all the medication from high blood pressure, high cholesterol, diabetes leaves him with e.d.He won't stay on a diet to fix these things, won't take viagra even though the doctor gave it to him, and I'm desperate for a decent sexual relationship.Any help, besides a friend with benefits, which I have tried but just left me guilty?
