" When we are children, play comes to us naturally, but our capacity for play collapses as we age. Sex often remains the last arena of play we can permit ourselves, a bridge to our childhood. Long after the mind has been filled with injunctions to be serious, the body remains a free zone, unencumbered by reason and judgment. In lovemaking, we can recapture the utterly uninhibited movement of the child, who has not yet developed self-consciousness before the judging gaze of others. "
