Anyone that has spent time at a sex club can tell you that on average women are FAR more noisy during sex than men. This is old news but it’s also true in other primates. The reasons are still somewhat under debate:
Female chimps often cry out during sex to attract nearby males, but they keep quiet when other females are around so they don’t alert their competition, a new study finds.
The function of copulation calls made by female primates (a group that includes lemurs, monkeys, and apes, such as humans and chimpanzees, our closest relatives) has been debated for years.
…
“The female chimps we observed in the wild seemed to be much more concerned with having sex with many different males, without other females finding out about it, than causing male chimps to fight over them,”
Female monkeys may shout during sex to help their male partners climax, research now reveals.
Without these yells, male Barbary macaques (Macaca sylvanus) almost never ejaculated, scientists found.
There are lots of topics for discussion here but the thing I find most interesting is that this is something apparently hardwired into the brains of many primates. I’m certain most women don’t consciously think, “I’m going to make a bunch of noise during sex to attract more men so they can have sex with me too.” However I wouldn’t be surprised if there are a fair number that have had occasion to think, “Maybe if I make some noise this guy will come and it will be over with.”
