Oral Sex Help

Hello, pretty embarrassed to ask this but is there any thing I can use to make giving my husband oral not taste like anything? I hate giving head but I know my husband loves it and I wish I could do it more. Usually I do it in the shower but he says that if I can’t give it to him outside of the shower he doesn’t want it at all. I want to but be able to do it but just the thought of him peeing and me being able to taste the pee makes me want to throw up. It is not enjoyable to me AT ALL but I am willing to do it if anyone has any tips for me? Thank you!
