The anus and genitals do not have a very large representation in the
somatosensory cortex. You don't need high resolution there :-)

They are more than that. I agree that these areas might be part of the
circuit, but most brain systems are distributed over many parts of the
brain, not just one. So the same circuits most likely also contain
neurons in the frontal cortex, the association areas, limbic system
and everywhere else.
