well ok I should probably note that the research I’m referring to was done with sheep and goats and can only really be applied as a hypothetical explanation for women’s openness in sexuality (more similar findings about this can be seen with the case of Lucy the chimp- see: Lucy: Growing Up Human [Temerlin, 1975] if you’d like some extra reading). I’ll describe it as best I can, though.
In the study, newborn sheep and goats where switched at birth, so the sheep were raised by goats and the vice versa. Once they reached sexual maturity, they were reintroduced to their biological species. What was interesting about it was that both the male sheep AND goats had no interest in the females of their biological species- suggesting that they were much more motivated by “sexual imprinting” in which their sexual behaviors were influenced solely by what they saw and were exposed to whilst growing. The females of both sheep and goats, on the other hand, were sexually open to both species and generally had more erotic plasticity!!
So it’s not quite about women but it is very similar to patterns we’ve observed in human females and that’s neat
