Does anyone else find it disgusting when the seme licks the ukes butthole?

I hope I don't get hate for this but like if I don't know if the uke washed his butt then I feel disgusted. The reason is because if it doesn't show or say anything about washing their butt then i start thinking something like: No seme your licking the poop! It's getting in your mouth! Stop!
Even if the butthole looks clean I would still think that. I need the uke to say that it's clean to know it's clean.
