Help? What can I do to make my husband want me

My husband had a accident that affected his manhood when we started dating. It’s been 6 years and I’ve been so patient with him and his recovery but he can’t even stay hard long enough for me to enjoy sex. He barely gets turned on and I feel like we had more sex pre marriage. I’m young and hot but I feel so pathetic because we barely have sex and I’ve verbally spelled out the issue I have but nothing seems to be changing. We argue more because there is so much built up tension and he always says he’ll work on it but he talks more than performs. I’ve straight up asked him if he has performance anxiety and he didn’t really want to admit it but I’m sure he does. How can I help? I’m super frustrated and always dream of passionate sex and fantasize about how good other people have it. I feel guilty but I can’t help it I deserve a better sex life than this
