It likely has to do with the “scent” of the female and perhaps some pheromones. You know how animals piss on their territory? Some animals shit on it. If we observe jeets and pakis, we see that they mark their teritory by shitting everywhere.
My theory is that male attraction to the anus has to do with “altering” the females scent, by using the penis. Did you know that penises contain the scent of the male, and the majority if the pheromones? That is one of the reasons women like rubbing penises on their faces. Ask any woman and she will tell you, she loves the scent of the penis. It is like catnip for women. That is also why they like sucking on penises.
The penis is also home to many scent inducing bacteria. The combination of phermones and these bacteria, which differ from male to male, creates a unique scent.
Rubbing the penis inside the anus and intestine of the female likely changes the bacterial composition of the female’s gut. And thus, it changes the smell of her farts and her poop. It likely also “adds” part of the females scent to that male’s penis, which is why men say, “smell my finger” to denote sex with a female. These scent changes all indicate that the female has become part of a male’s harem.
In other words, “imagine the smell”.
