Motherhood and the Relationships of the Sexes
I believe that the woman’s superiority in this matter of constancy, even when it is present, is not fundamental to the female character any more than it is fundamental to the character of the male, and, indeed, I am inclined to think that it is the man who in his desire is more bent than woman towards complete faithfulness in the sexual partnership, and if it is the wife who more often is apparently and outwardly constant in marriage than the husband, it is because such conduct is expected of her and has been forced upon her by the conventions of her life.
