Women naturally seek commitment from men as partners to help raise children, as women can only release one egg per month. In contrast, men can release vast numbers of sperm and are biologically driven to attract as many women as possible to reproduce, as there is no limit. This diversity in human nature psychologically impacts men and women's behaviors, making women desire commitment and men attraction to multiple women. True challenge is for men to control this natural desire for other women to sustain committed relationships and society for child rearing.
