YUP I fuckin LOVE the smell of my own crack/nut sack at the end of the day. I often will run my hand down there and smell my fingers. Girl's crack after a work out or at night is the same. Simply intoxicating. And as long as a person hasn't pooped all day, it's pretty safe to bury your face in there
I hear what you're saying, but I've eaten ass for decades and I've never had an issue despite eating asses that, in your words, was after work and even post-potty. Being 'immaculate' is too sterile for those of us who prefer it in its natural state, especially the natural odor of the area. (me, that orifice is treated with exalted reverence by myself and those women I've been with and if it has ever been messy, a few splashes of water (soap dries out the skin too much) will do. Soap covers the natural scent of that orifice and the chemicals you'd ingest are far more harmful. Most Gen X, Millennial a Gen Z I've had the privilege of performing anilingus with, actually are more aroused if that area is 'au naturel.' I take great pleasure in performing it as that natural scent is that person's true essence that they are sharing with you. A person who allows you to experience that most intimate orifice in its natural state is being vulnerable and I deeply respect and love that.
