Spouses urinating and excreting on each other during sexual relations

Q: My husband insists that we do golden shower (where he urinates on me and vice versa) and scat (where he stools on me and vice versa) during foreplay as this is his fetish. Is it allowed that we do this? I am scared that he maybe hit and abuse me if I refuse him of this pleasure. He also wants to ejeculate semen in my mouth when he cums. Is it allowed for him to do this because he says I will be getting sin and punishment if I do not obey him. Please give me some advise on what to do.
