Derek Haven was a man. A big strong man who was also very handsome.
Even from an objective point of view. Anybody with a heartbeat would have to admit that. As far as Emily was concerned, even an inanimate object, would be able to tell just how handsome Derek was. When it came to the male of the species. He was one of those who had gotten some really good genes from both his parents.
A real man amongst men. And that brought Emily back to her original point. Derek Haven was a man.
And being a man, he had to deal with certain things that Emily did not have to worry about. One of those things happened to be morning wood. The very thing that had happened on Sunday morning. She should not have run.
