  Trivers (1972) added considerations of parental care to Bateman's argument. Trivers argues that females generally invest more than males in reproduction, not only in terms of creating large eggs, but also in the development and care of offspring. As a result, females ought to be even choosier regarding mates and become an even more limited resource for males. Again, it follows that males are motivated to mate with as many females as possible and females are motivated to resist male advances in the hope of choosing the best mate possible. This is correlated with and reinforces stereotypes of males as active, promiscuous, and competitive, and females as passive, coy, and nurturing. The rhetoric of the coy female and the promiscuous male is decreasing but is still common among many accounts of sexual selection.
