I lost 2 relationships for this very reason. I couldn't handle making myself have sex so it happened less and less frequently. Until it stopped. And they left me because of it. I am relieved. Because I don;t have to be afraid that I have to have sex tonight to save my relationship. Because I don;t have to have sex at all. The sad truth is that it will hurt your relationship at the very least, if not destroy it. I don't know how to make it better for us, or even if it can be better. Maybe there is no fixing us.
