According to Dr RM Ellsworth – from the Department of Anthropology, University of Missouri – women who fake an orgasm are more likely to be unfaithful to their partners.
In a study, the research team created a questionnaire and asked 138 women and 121 men currently in a romantic relationship to contribute to it.
They were asked about their sexual activity and whether or not they have cheated in the past.
Results found that the frequency of orgasm in women was not connected to fidelity.
Instead, infidelity was associated with women who frequently lied about experiencing an orgasm.
According to the study:
Faked orgasm was associated with female sexual infidelity and lower male relationship satisfaction.
Overall, results were in greater support of the sire choice signalling hypothesis than the female fidelity hypothesis.
