Compulsory Monogamy: Exclusivity, Social Norms, and Relationship Choice

Examples may include assumptions such as:

• serious relationships must be monogamous;
• non-monogamous people are incapable of commitment;
• jealousy proves love;
• marriage should always require sexual exclusivity;
• people who want multiple consensual relationships are irresponsible.

The concept does not argue that everyone should practice non-monogamy.

It argues that monogamy should be a genuine choice rather than an unquestioned social requirement.

People may grow up assuming that adulthood should follow a particular sequence:

• find one romantic partner;
• become exclusive;
• marry;
• prioritize that relationship over most others.

For many people, this structure fits their genuine preferences.

The problem arises when alternative consensual relationship structures are treated as automatically immature, immoral, unstable, or inferior.

Social pressure may also make people remain in monogamous arrangements they do not actually want because they fear rejection or stigma.

Compulsory monogamy refers to the expectation that everyone should choose that structure.

A monogamous relationship can be healthy and freely chosen.

Likewise, someone may strongly prefer exclusivity without being judgmental toward other relationship forms.

The distinction is therefore between:

• chosen monogamy, based on preference and agreement;
• compulsory monogamy, based on social pressure or assumed superiority.

Criticizing compulsory monogamy is not the same as criticizing people who prefer monogamy.

Examples include:

• polyamory;
• open relationships;
• some forms of relationship anarchy.

These arrangements differ from cheating because they involve knowledge and agreement.

Non-monogamy is not automatically more liberated or ethical than monogamy. Either structure can involve:

• healthy communication;
• poor communication;
• respect;
• coercion;
• jealousy;
• dishonesty.

The ethical quality of a relationship depends on how people treat one another, not simply on whether it is monogamous.

Amatonormativity is the assumption that everyone should seek and prioritize a central romantic partnership.

Compulsory monogamy assumes that such a partnership should also be exclusive.

For example:

• expecting everyone to find a romantic life partner reflects amatonormativity;
• assuming that partner must be the person’s only romantic or sexual partner reflects compulsory monogamy.

A person can challenge amatonormativity by valuing friendship, chosen family, singlehood, or queerplatonic relationships.

A person can challenge compulsory monogamy while still strongly valuing romantic partnership.

Traditional relationship expectations may assume:

• heterosexual marriage;
• lifelong exclusivity;
• gendered household roles;
• reproduction within the couple.

Women may historically have faced particularly strict expectations of sexual fidelity, while men’s non-monogamous behavior has sometimes been tolerated more readily. This can create a sexual double standard rather than consistent monogamy.

LGBTQ+ people may also challenge conventional relationship expectations by creating family or partnership structures that do not follow traditional heterosexual models.

However, many LGBTQ+ people are monogamous and should not be stereotyped as non-monogamous.

A person should not be pressured into:

• monogamy;
• non-monogamy;
• polyamory;
• an open relationship.

For example, one partner cannot ethically use the language of relationship freedom to force another person to accept non-monogamy.

Likewise, a person should not be shamed into monogamy simply because it is socially conventional.

Healthy agreements may include discussion of:

• exclusivity;
• boundaries;
• emotional commitments;
• sexual-health practices;
• privacy;
• expectations about other partners.

Consent to a relationship structure can also change. If partners develop incompatible needs, they may need to renegotiate the relationship or decide whether to continue it.

For example, people may assume:

• jealousy always demonstrates love;
• multiple relationships prevent emotional depth;
• exclusivity guarantees loyalty.

These assumptions are not universally true.

A monogamous person may feel deeply secure without strong jealousy, while a non-monogamous person may maintain serious long-term commitments.

At the same time, jealousy is a real emotional experience that can occur in any relationship structure.

Relationship diversity does not require pretending jealousy, insecurity, or conflict never exist. It requires addressing them honestly rather than treating one relationship structure as automatically superior.

Marriage can affect:

• inheritance;
• taxation;
• healthcare decisions;
• immigration;
• parenting recognition;
• property.

These systems may give legally recognized couples advantages unavailable to other forms of intimate or caregiving relationships.

Critics of compulsory monogamy may therefore ask why one exclusive couple is often treated as the primary or most legitimate adult relationship.

However, debates about legal recognition are complex, and laws concerning marriage and multiple partnerships vary widely by jurisdiction.

Anyone who prefers exclusivity supports compulsory monogamy.
No. A personal preference is different from imposing that preference on everyone.

Rejecting compulsory monogamy means endorsing cheating.
No. Consensual non-monogamy depends on agreement, while cheating involves violating relationship agreements.

Non-monogamy is automatically more progressive.
No. Any relationship structure can be healthy or unhealthy.

Jealousy proves that humans are naturally monogamous.
No. Jealousy is a complex emotion and does not by itself determine an ideal relationship structure.

Everyone should experiment with non-monogamy.
No. Relationship autonomy includes the freedom to choose monogamy.

1. Compulsory monogamy treats exclusivity as the expected relationship model.
2. Criticizing compulsory monogamy does not mean rejecting monogamous relationships.
3. Consensual non-monogamy challenges the assumption that commitment always requires exclusivity.
4. Compulsory monogamy can overlap with amatonormativity.
5. A monogamous relationship can be freely chosen rather than socially imposed.
6. Relationship agreements should be based on consent and communication.
7. LGBTQ+ relationship diversity has contributed to discussions about compulsory monogamy.
8. Understanding compulsory monogamy helps explain how culture, intimacy, exclusivity, ethics, and relationship autonomy interact.

The concept encourages people to distinguish between monogamy as a valid personal preference and monogamy as an assumed universal requirement.

An inclusive approach supports relationship autonomy: people may freely choose monogamy, consensual non-monogamy, singlehood, or another relationship structure, provided that agreements are informed, voluntary, respectful, and consistent with the autonomy of everyone involved.
