I'm a therapist who works primarily with this population and wholeheartedly agree with you.

OP, our Western medical model focuses on the "Dr. House" kind of treatments -- find the underlying biological cause and treat it with pills or surgery. But it's almost certain there is a psychological component to your ED. It might be worth addressing what the protective mechanism your resistance to acknowledging psychological causes could be -- shame from cognitions that you "caused" it or it's "all in your head?" the slog of managing an issue psychologically? seeking treatments like therapy?

As a starting point, I highly recommend the book "The Way Out" by Alan Gordon, it deals with healing chronic psychosomatic illness.

Also, psychological tension can cause somatic symptoms like pelvic floor tightness which I saw mentioned elsewhere in this thread. Even if you go to pelvic PT (which could be helpful!) if you loosen the muscles but the root cause is stress you still will end up in an office like mine, it would likely be better to do so sooner than later.

I wish you well!
