I never thought I'd write those two little words. But a new study (yeah) has looked at heterosexual women's copulatory vocalizations and concluded that they are sham. Yes, sham! Hetero women scream and egg men on to get it all over and done with. It's manipulative, my sweeties:
More detailed examination of responses during intercourse revealed that, while female orgasms were most commonly experienced during foreplay, copulatory vocalizations were reported to be made most often before and simultaneously with male ejaculation. These data together clearly demonstrate a dissociation of the timing of women experiencing orgasm and making copulatory vocalizations and indicate that there is at least an element of these responses that are under conscious control, providing women with an opportunity to manipulate male behavior to their advantage.
It could be that "manipulate" is a scientific term here, something that even male subjects might stoop to. But then perhaps not, because of that "to their advantage" tail to the sentence. It's impossible for the researchers to imagine that some women might vocalize for reasons of love or for reasons of increasing the pleasure of their male partners. Just to offer other explanations than manipulation. (Or if they suddenly remembered that they left the soup boiling on the stove.)
I think that these results are based on questionnaires that women were asked to fill in later, not during the sex. If there are copulatory vocalizations which are involuntary consequences of the female orgasms or their approach, those vocalizations might not be remembered by the woman at all, what with her having fainted from pure bliss, say.
