Two researchers from the University of Central Lancashire, in Preston, England have some news heterosexual men might not be anxious to hear.
A woman's noises during sex often don't correlate with them actually having an orgasm.
The study found that women's "copulatory vocalizations" were reportedly made most often before and during male ejaculation, not necessarily during their own orgasm.
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.
According to the report, women were least likely to experience orgasm during penetration by a man.
They were more likely to have an orgasm after self-manipulation, manipulation by their partner or oral sex, in that order.
A 2009 study found that female orgasm eludes the majority of women.
There's also evidence that meditation and orgasm feel the same to the brain.
