>>13075946Strong and assertive males have a higher chance of successful hunts, get a larger share of collectively hunted prey, and can better protect their offspring from rivals or predators. Thus, in species where males take part in the upbringing of their offspring, either by providing food, offering protection or even outright raising them themselves (which is the case for most mammals), females have an interest in strong and dominant males.
This also means that if a male is capable of overpowering a female, he basically has proven himself to be "worthy". If she already has offspring, there's even a chance that he adopts and cares for them as if they were his own.
Thus it would be in the interest of the female to stop resisting the mating attempt by the male and accept him - otherwise, if the female keeps her resistance up, he might figure she's not worth the hassle and take off, leaving her without a mate and potential protector/food supplier.
This is how sexual masochism and rape fantasies have developed in women. They basically want to be roughed up and overpowered by a strong and healthy male. Note that women's rape fantasies always include a strong and attractive male. No woman fantasizes about being the sub to some limp-wristed basement dweller.
