According to a new study, published in the Archives of Sexual Behaviour, women who regularly fake orgasms were less faithful.
The survey studied 138 women and 121 men in heterosexual relationships and asked them about climaxing and cheating.
While the intensity and frequency of female orgasms had little bearing on whether women had cheated before or were likely to cheat in the future.
However, a specific connection between the amounts of fake orgasms a woman does during climax can identify if she was to cheat.
It is revealed that the more orgasms a woman had faked, the more likely she was to have done the dirty in the past and the more likely she was to cheat again in the future.
In fact, according to S** expert Dr Tammy Nelson, the more women have faked it than not – with a staggering 80 per cent admitting doing it.
Previous studies have shown that women who fake it feel unsatisfied by their partners, or unable to communicate what they want in the sack – which may explain the need to find pleasure elsewhere.
