The character discovers his current life to be tamed and lacking. He allows himself to play the part of an average white collar worker because he assumes that's what society demands out of him. His work, and current girlfriend are symbols of that entrapment and compliance.
His new love interest helps him to discover the many rewards life has to offer, along with revealing the more visceral side of him, that made for great sex. The sex is really, really great for him.
He is born again through boning, and finds life that much more easier to tolerate with a person he genuinly cares about.
The end.
