How do I help my husband?

I am 42 and my husband is 57 with ED.  It's been a 6 year journey to today.  We've tried all the pills, lotions, potions, injections, etc.  Nothing seems to work anymore.  His desire is there but it just doesn't happen very often anymore.  He does have high blood pressure, cholesterol and diabetes (takes pills)  He is thinking that surgery is the only option left to do.  It's so permanent and I'm not sure he's ready for that.  Nor I for that matter.  I miss sex don't get me wrong. But it's really seperated us and made it uncomfortable to be intimate at all.  Anyone else with similar issue?
