Do you think it's possible to have a long term relationship with someone without having sex?

I’m in a relationship with a guy, have been seeing him for 1½ yrs. We sleep together, but don’t have sex. He suffers from ED and he has very low libido. He has tried the usual treatments and nothing worked and it seems he has no interest in trying anything else. The problem is I have what I think is a normal sex drive and I miss the intimacy. I am very much into monogomy so trying to found someone just for the sex is not an option( this was suggested to me by a friend) Is it possible to have a nonsexual relationship with someone. I’m not referring to a regular friendship
