I’ll always hale the human butt on centaurs.
To prevent myself from getting into arguments about that (again), I just tell myself the taur butt is just specialized muscle groups to support the human half.
You can still stick your dick into it if you want to, but it’s basically paizuri (titty-fucking) at that point.
