The original equipment doesn't work or I'm impotent, can I change it?

My physical health is the worst it’s ever been. I’ve stopped driving everyplace and instead walk. I take heavy duty medication, nothing I can do about that. The one ED pill didn’t work, I want to try another but it’s $38 dollars a pill, insurance doesn’t cover it. I would not care so much if I had intimacy but I’m sure it’s a let down for her (whomever it may be) the last woman had a problem w/ it but never actually said it. But it was a fling (morality question) but it may not have been if circumstances were better. All I can think of is get my health back and to work with the doctor on meds. Is there an aspect I’m missing?
