What does research say about cheating in monogamous relationships?

• A. Cheating is rare and usually involves only one partner.
• B. Many individuals with monogamy agreements may cheat, often without practicing safe sex.
• C. Monogamy guarantees fidelity.
• D. Cheating always includes multiple partners.

Answer: (B)

Research shows that fidelity in monogamous relationships is not guaranteed. People who are in monogamy agreements may still engage in sexual or emotional affairs, sometimes with outside partners and sometimes with just one person, for a variety of reasons such as dissatisfaction, opportunity, or evolving boundaries. Importantly, when cheating does occur, it can involve unsafe sex, making protection and STI risk a real concern. This nuance—that monogamy agreements don’t automatically prevent cheating and that outside sex can occur without protection—best captures what research finds. The other statements oversimplify the issue or contradict what studies show: cheating is not rare, monogamy doesn't guarantee fidelity, and cheating does not always involve multiple partners.
