Not sure what to do?

That is very encouraging that your night time erections have returned.
The exercise has most likely helped, even though it was intense.

Here is a link to that post.

I mentioned pelvic floor issues mainly because you seemed to have reached a dead end.
I believe it is a real thing, but cannot say if it's part of your problem or not. But worth considering.

Ok I’ll have a look at that thread...one more thing. Do you think the problem I have could be anything to do with blood pressure possibly? Like different pressure when sitting vs standing??? The doc said my blood pressure was normal but he took it whilst sitting down? Has anyone heard about blood pressure being a problem when finding it difficult to maintain an erection whilst stood up?

From what I understand I think only orthostatic hypotension could cause this, but there would be a number of other symptoms present too.
So I doubt it.
