Condom use errors among sexually unfaithful and consensually nonmonogamous individuals.

This research involved comparisons of the condom use behaviours of people who are in monogamous relationships but who have engaged in extradyadic sex (i.e. committed infidelity) to those who are in consensually nonmonogamous (CNM) relationships. Consensual nonmonogamy is the practice of openly having multiple sexual or romantic partners simultaneously, with the full knowledge and consent of all participating partners. Participants in CNM relationships used condoms more correctly in their last instance of intercourse than those who were committing infidelity.
