Monogamy is one of the most debated, and often misrepresented, relationship concepts in human history. For several centuries monogamy has been the assumed gold standard for how romantic relationships work, lauded in movies, novels, religious structures, and even cultural traditions. While many presumptions exist around monogamous relationship structures, with changing social assumptions around relationships today, people are asking deeper questions around monogamy.

In this all-encompassing blog, we will discuss the evolution of monogamy, types of monogamous relationships, the challenges of monogamy, and contemporary forms of monogamy in the modern world. If you are reading this out of curiosity, questioning your own beliefs, or reading for someone else, this blog will help break it all down.

What is Monogamy?

Monogamy simply means relating to only one romantic or sexual partner at a time. It is derived from the Greek words monos (single) and gamos (marriage) which together translates to: one marriage. But in most contexts today, it means more than just a legal marriage; it means to have both sexual and emotional exclusivity.

Monogamy comes in at least two forms:

• Social Monogamy: Partners cohabit, co-parent, or share domestic life.
• Sexual Monogamy: Partners are sexually exclusive to each other.

Some people also follow the practice of serial monogamy, where a person has multiple exclusive relationships one after the other without ever overlapping partners.

What is Monogamous Relationship?

A monogamous relationship usually means:

• Emotional and sexual exclusivity
• A long-term commitment (but not always marriage)
• Trust and boundaries committed to one another
• Cultural or religious commitment

People choose monogamy for many reasons: emotional security, religious beliefs, simplicity, or personal choice.

What is the History of Monogamy?

Although many ancient people engaged in polygamous relationships (multiple spouse), monogamous practices became predominant for a variety of reasons:

• Ancient Greeks and Romans – They encouraged monogamous relationships primarily because it was easier for them to distribute inheritance, thus avoiding disputes.
• Christianity and other Abrahamic religions – Reinforced a one-man, one woman doctrine in the name of morality, and made it part of the divine plan for humanity.
• The rise of individualism and capitalism – This established family in a nuclear structure, placing monogamy as an ideal practice.

Interestingly, polygamy still remains legal or culturally acceptable in over 50 countries mostly because of religious practices or developments in tribal systems.

Is Monogamy Still Normal?

Yes, monogamy is still the “normal” model of relationships around the world, but is rapidly being challenged. 

In recent years we have seen non-monogamous relationships blossom. There is a heightened interest and participation, especially from millennial and Gen Z demography. Various studies suggest 1 in 5 people in the U.S. have participated, to some degree, in some form of ethical non-monogamy (ENM).

That doesn’t mean monogamy is going away; it means there are more choices.

What is Non-Monogamy?

Non-monogamy refers to any relationship structure in which emotional or sexual exclusivity is not required.

Some examples of non-monogamous relationships are in the form of:

• Polyamory: Loving more than one person at a time (People involved understand and agreed to this form of relationship structure.)
• Open Relationships: Being monogamous with regard to the relationship, but allowing sex and emotional experiences with others.
• Swinging: Engaging in sex with someone else, usually as a couple.
• Relationship Anarchy: Avoiding hierarchy and labels in emotional and sexual relationships.

Non-monogamy is not the same thing as cheating. The main difference? Consent.

What is Ethical Non-Monogamy (ENM)?

Ethical non-monogamy is the practice of consensual, honest, and respectful non-exclusive relationships.

Important components include:

• Transparency: Everyone involved is aware and agrees to the relationship.
• Boundaries: Everyone involved has their own boundaries and establishes rules that they all respect (e.g., “no sleepovers”, “emotional limits”, etc.).
• Autonomy: Everyone involved is free to choose the way they romanticize/sexualize in each of their relationships.
• Ongoing conversation: People find that boundaries and needs are constantly changing; discussion should happen as close to the current moment as possible.

ENM is not a “way out” to cheat. Indeed, lots of people in ENM relationships suggest that communication is significantly higher than between people in monogamous relationships.

What are the Myths About Monogamy?

Myth: Monogamy means you will never want to be with anyone else.
Fact: Not true. Attraction does not disappear, it is about what you do with it.

Myth: Monogamy means that you will never cheat.
Fact: Cheating can happen in any structure. Trust and communication are more important than labels.

Myth: If someone doesn’t want monogamy, they can’t commit.
Fact: People who practice ENM can develop deep and long-lasting relationships. It is not about fear; it is about fit.

What are the Challenges in Monogamous Relationships?

Monogamy does relate with its own challenges:

• Feeling bored or stagnant sexually
• Unrealistic expectations (“You must satisfy all of my needs”)
• Jealousy and insecurity
• Not answering emotional needs

The good news is that every one of the challenges mentioned can be addressed through healthy communication, therapy, and conscious effort.

How to Decide What is Right for You?

Ask yourself:

• Do I value exclusivity or do I feel restrictive when exclusivity is applied?
• Do I thrive when having emotional intimacy with one person?
• Am I ownley about one or multiple connections, or is that too overwhelming?
• Have I shared these ideas with my current partner or a potential partner?

You do not have to “pick sides.” Relationships are very personal and there are no right and wrong ways to be in relationships, only growth!

Whether you flourish in a one-on-one relationship or feel compelled towards a more expansive form of connection, your relationship style should be based on honesty-with yourself and others.

The future of love is neither monogamy nor non-monogamy; it is authenticity. And that begins with asking the right questions, like you just did.
