Women who frequently fake orgasms are more likely to cheat on their partners, according to a new study on female sexuality published in the Archives of Sexual Behavior.
The study's authors, Ryan M. Ellsworth and Drew H. Bailey, questioned 138 women and 121 men involved in romantic relationships in attempt to discover an evolutionary purpose for the female orgasm. They hypothesized that the orgasm may have evolved in order to keep women from straying.
According to their research, however, the frequency (or intensity) of female orgasms had no effect on whether the women were likely to cheat -- but the frequency of faking the Big O did.
Specifically, "It was found that faked orgasm was positively associated with the likelihood of past, present and future sexual infidelity," the researchers wrote.
The finding goes against other studies that suggest women may fake orgasms in order to protect the male ego and keep their guy more interested in the relationship.
