"Simple Song" by Marge Piercy --> meaning?

Question

what does this poem mean?.. more specifically the last stanza?

When we are going toward someone we say
you are just like me
your thoughts are my brothers
word matches word
how easy to be together.

When we are leaving someone we say
how strange you are
we cannot communicate
we can never agree
how hard, hard and weary to be together.

We are not different nor alike
but each strange in his leather body
sealed in skin and reaching out clumsy hands
and loving is an act
that cannot outlive
the open hand
the open eye
the door in the chest standing open.

bodies get in the way
of the hearts intention
but the desire
lingers
so we open ourselves
to the pain
