Sex therapy not working for ED

I have chronic ED which only seems to happen in the bedroom with my partner. I get so anxious and terrified and it’s just getting worse and worse, to the point that it happens during any form of intimacy at all.

I have seen therapist after therapist for over 4 years and it’s getting worse if anything. I need some advice as I don’t know what to do, I don’t understand how I can get worse.
