The phallus is essentially social.
But the anus—that’s mostly private.
When you talk of the constitution of a private person, that’s the anus.
And the public person, that’s the phallus.
So you could say that exposing one’s phallus is a shameful act—but a
glorious one, too,
and every man has a phallus
that guarantees him a social place.
And every man has an anus, too,
which is truly his own,
in the most secret depths of his own person.
