SUMMARY :
Infidelity is a complex topic. The objective of this work is to describe and to discuss female sexuality, the official bond and the extramarital relationship, in 11% of women who were unfaithful in a sample of 200 consecutively dysfunctional women who related, of their own free will, their infidelity during sexual therapy.
The majority of unfaithful women from this sample, beyond the sexual involvement, had an affective involvement with their lover, as passion was reported by 59.09% of them.
The feelings in relation to the lovers were a pre-requisite for having sex but didn't allow for the pleasurable enjoyment of sexuality.
