Need help

So my husband told me a dark secret that he is addicted to sex, and that he needs to cum everyday. My sex drive has been up and down since I gave birth 3 months ago. I have been feeling so much pressure to try to give him his pleasure everyday, but I have been failing. Then when I do want to have sex, I feel sick when I try oral because all I smell is urine down there from him not cleaning himself. Then I lose the desire to do anything. When this happens, he leaves and makes me feel bad for not finishing. This has been stressing me out for a while now, and I'm afraid he'll eventually grow tired of me and move on to another girl. What do you think I should do?
