The most intimate and liberating coitus results in one person inhabiting their own self, their own body, their own mind, their own emotions, as completely as it is possible to do, with the other person as willing instrument to achieve this self-completion.
We do not conjoin to merge, we join to experience ourselves and the moment fully.
That is the other dichotomy suggested but not addressed: between waiting, alone, and being present, with someone else. The author seems wholly unaware, perhaps deliberately as it would be inconvenient to their thesis, that it is possible to be fully present alone, fully engaged in a moment independent of anyone else, and likewise possible to wait, lonely, while with another, perhaps for very long periods.
In the author's waiting, there is no communication, no express of desire or intent. One simply waits, and hopes. A life experienced so passively is perhaps not lived. Waiting and silence have their place, but life is more complex than that.
