Anything ass related in sex is disgusting in my opinion. I get it in porn since from what I know they actually get it professionally cleaned and checked by medical professionals prior to conducting those scenes.

But doing it to random or barely dated women/men that just used plain old tissue to wipe that part hours or days before you eat it? Disgusting. 


I get it you can clean the outside with soap and other hygiene products but it's still pretty disgusting.

If you're doing it right then you wash pretty thoroughly inside and outside. Douches and enemas are very common in anal
