§ 176
The unconscious polyandry of the average married woman is absolutely proved if she does not regard her husband as satisfying in every way. If there is the remotest doubt of this, if she has the slightest repulsion or disinclination or aversion to any feature, act, mannerism or personal quality of his, she is withholding from him, possibly blamelessly because unconsciously, a feeling which, as she cannot give it to him, she must and does unwittingly give to some other man either seen or dreamed of. Absolute surrender on her part to one man is essential for a strictly monogamous union, a complete union entirely excluding the appeal of every other man under the sun. Any reserve whatever on her part is a reserve that will be kept by the unconscious part of her solely for the use not of her husband but of some other man possibly not yet seen by her; later she may meet him.
How can a woman give herself, if she has keen sense discrimination, to a man who isn’t strong, isn’t clean, isn’t well-dressed, isn’t generous and loving? If she has this fine discrimination she will not run the risk of approaching a marriage with such a man. If a man of undeniable strength (mental, not physical) makes love to her, his sincerity and the strength of his desire will enable her to change other characteristics in him before marriage.
