Cannery Row by John Steinbeck:
Henri has been living in and building his boat for ten years. During that time he had been married twice and had promoted a number of semi-permanent liaisons. And all of these young women had left him for the same reason. The seven-foot cabin was too small for two people. They resented bumping their heads when they stood up and they definitely felt the need for a toilet. Marine toilets obviously would not work in a shore-bound boat and Henri refused to compromise with a spurious landsman’s toilet. He and his friend of the moment had to stroll away among the pines. And one after another his loves left him.
Just after the girl he had called Alice left him, a very curious thing happened to Henri. Each time he was left alone, he mourned formally for a while but actually he felt a sense of relief. He could stretch out in his little cabin. He could eat what he wanted. He was glad to be free of the endless female biologic functions for a while.
