Women fake orgasms due to fears that men will cheat
WOMEN fake orgasms because they are worried that their lover will be unfaithful, scientists have concluded.
They also found that the more often a woman fakes her sexual climax, the more successful she is in keeping her man.
Researchers in the United States questioned 453 heterosexual women between 18 and 46 in committed relationships which had lasted a minimum of six months.
More than half of the women (53.9pc) reported having pretended to reach orgasm with their current partner.
The scientists noted that “women who perceived higher risk of partner infidelity were more likely to pretend orgasm”.
They also found that a woman who had faked an orgasm at some point was more likely to develop suspicions about their partners' fidelity than a woman who had never done so.
Farnaz Kaighobadi, of Columbia University in New York state, Todd Shackelford and Viviana Weekes-Shackelford, both from Oakland University in Michigan, led the research.
They found a number of tactics were developed by women to keep a man they were concerned might stray.
Such devices included making more of an effort with clothing, following their man’s movements and confronting potential rivals who looked his way.
Scientists have previously argued that women who reach orgasm are more likely to keep their lovers interested.
Dr Kaighobadi said her research suggested that the ability of women to orgasm could change over time to give them an evolutionary advantage.
The study was published in The Archive of Sexual Behavior.
