Fidelity in a relationship means different things to different people. For many, the idea of fidelity means no sexual contact outside the relationship, but that isn’t true for everyone. Open marriages can work when fidelity is given a broader definition. Fidelity in open relationships means that the partners will be completely open and honest about their sexual needs, attractions and experiences. Couples often seek approval from one another before engaging in extra-marital sex. And different couples have different rules about how much they share about their sexual experiences outside the marriage. As long as both parties commit to this ideaof fidelity, the marital relationship functions just as any other would.
