there are studies showing women actually prefer more masculine men during ovulation, the few days when they can actually get pregnant each month. At other times of the month, they are more attracted to men who are "good providers," which is an evolutionary adaptation that runs counter to monogamy. Essentially suggesting that women, who are mammals that conceal "being in heat" unlike other mammals, can choose to become pregnant with masculine men when they are actually able to get pregnant, but for the rest of the month, they are attracted to the men who they can rely on to provide for them. Birth control might alter this, I'm not sure. But it's an interesting sexual selection rabbit hole to investigate.
