What Therapists Need to Know About Nonmonogamy

Three friends watch a sunset on the beachTherapists who have not had a great deal of experience or education around the issue of nonmonogamy may worry about their ability to work effectively with individuals or couples who have, or are considering, a nonmonogamous arrangement. We all have preconceived ideas and judgments about what makes relationships effective, and it is important to examine how those notions compare to research and clinical experience.

Prevalence of Nonmonogamy

One important point to consider is that you may already be working with someone in a nonmonogamous relationship. Many individuals who are in open relationships or other nonmonogamous relationship configurations report a reluctance to disclose their relationship status to their clinicians for fear of being judged. With some professionals openly acknowledging an inherent bias against nonmonogamy as a potentially healthy and satisfactory arrangement (Greenan, 2003, and Ruskin, 2011), and with anecdotal reports of therapists insisting upon sexual non-exclusivity as either the root cause or at least a symptom of dysfunction within a relationship, people seeking therapy have reason to be wary. When beginning treatment with a new individual, it may be beneficial to be explicit in asking if they are monogamous or not.

Some segments of the population are more likely than others to be in polyamorous or nonmonogamous relationships. Studies have shown that same-sex male couples, for example, are more likely to report an agreement that allows for sex outside the relationship than either opposite-sex couples or same-sex female couples (Gotta et al., 2011). Additionally, older same-sex male couples seem to be more likely to have such an agreement than their younger counterparts (D’Augelli, Rendina, Sinclair, and Grossman, 2007; Wheldon and Pathak, 2010). This may reflect a change in values related to monogamy among younger cohorts of gay and bisexual men, or it may be related to the finding that most open relationships do not begin open (Hickson et al., 1992; Spears and Lowen, 2010), so some same-sex relationships among younger men may transition to a nonmonogamous agreement later.

Benefits and Challenges of Nonmonogamy

It is also important to note that research published on nonmonogamy frequently finds that there is no significant difference on measures of satisfaction and adjustment between partners in open relationships and their monogamous counterparts (Blasband and Peplau, 1985; Kurdek and Schmitt, 1986; Wagner, Remien, and Carballa-Dieguez, 2000; LaSala, 2004; Hoff et al., 2010). So while notions that nonmonogamous relationships are less fulfilling or healthy than monogamous ones remain prevalent, they are simply not supported by research.

There are additional challenges, as well as benefits, that partners in nonmonogamous relationships may experience. A therapist who presumes that nonmonogamy is less functional may have difficulty recognizing those benefits, while a therapist striving to demonstrate an affirmative stance may have a harder time seeing the challenges. A small collection of both the potential benefits and challenges is listed below:

Potential Benefits

  • Opportunities for more honest discussion about sexual needs and fantasies
  • Increased possibility of exploration of emotions such as jealousy and insecurity
  • More deliberate attention paid to identifying and highlighting the primacy of the relationship

Potential Challenges

  • Greater possibility of jealousy and other uncomfortable emotions
  • Increased risk of sexually transmitted diseases and infections
  • Stigma and judgment from peers and family

All Relationships Are Unique

Another important thing to keep in mind is no two nonmonogamous relationships are identical, just as no two monogamous relationships are identical. Some relationships have strict rules governing sex or emotional connections that occur outside of a primary pairing, while others have few to no rules, and others still do not recognize a primary pairing at all. Partners in nonmonogamous relationships may benefit from exploring the rules they have in place to determine what function they are designed to serve, and whether they are effective in meeting that goal.

Just like with monogamous relationships, no two nonmonogamous relationships are identical.

It may be helpful for therapists to become familiar with some of the common terms associated with different types nonmonogamous relationships (open, poly, monogamish, etc.) and to be able to identify the differences between them. Most helpful, however, would be to remain open to the possibility that a relationship may not fit neatly into any of the most common categories. Below is a list of generalized definitions for some common terms a therapist might encounter:

  • Open relationship: A relationship in which the partners agree that sexual activity with people outside the relationship is acceptable.
  • Poly or polyamorous relationship: A relationship in which multiple partners participate. This may mean that three or more people form a primary relationship, but it may also mean that a primary relationship exists between two people, and each has one or more additional partners.
  • Triad: A polyamorous configuration in which three partners are all in a relationship with one another.
  • Vee: A polyamorous configuration in which one partner is in a relationship with two other individuals, but those individuals are not in a relationship with one another.
  • Monogamish: A mostly committed partnership in which occasional exceptions are made for outside sexual activity.
  • Emotional fidelity: A requirement that relationships with others outside the primary relationship not be emotional in nature.
  • Compersion: A feeling of pleasure that comes from seeing one’s partner in a relationship with another person.

    So from a professional stance I am assuming that it would be looked down upon to tell a couple, look, I don’t believe what you believe in this venue so it would be best to find a different therapist?

    I would bet that as a therapist you are always going to hear quite a lot of things in your practice, some of the things that you will be able to relate to and then there will be others that you will not. But your job as a therapist is not to agree with everything that your client tells you; but to help them with the things that they are struggling with in their own lives. You have to be able to separate those things from the professionalism that you are expected to provide to them.

    Joshua, Sienna, and Anne: I think you all make great points about the role of the therapist’s personal values and biases. I would add that therapists do have an ethical obligation to operate within the boundaries of their competence. Part of that might mean that, if they are so uncomfortable or in such disagreement with a client’s decisions that they cannot do good work with them, they should refer that client to someone who will be a better fit. My previous article on this subject talks a bit about that: https://www.goodtherapy.org/blog/can-open-relationships-work-for-gay-men-0113164

    They should know that this is actually a relationship style that works for many many people, especially for those of us who want the connection with that right person but we are not necessarily looking for that “forever” kind of commitment.

    I have been in both types of relationships but I can truthfully say now that I feel a whole lot more secure about MYSELF when engaged in a one on one relationship. I do way too much questioning and second guessing when the relationships have been more open and I just never really feel that good about who I am and the others that I am involved with I guess when we try something like that. I think that the older and more mature I get that I see this probably isn’t for me.

    but you kind of have to know going into this that you are going to come across people from all different walks of life and different belief systems than what you have, right?

    so i can seehow it could be easier to talk about sex things

    when you are actively in
    two or more relationships
    but also a larger opportunity
    to make someone angry

    Wondering why swingers were not mentioned in this article? There’s many thousands of us in the US and I believe we are considered non-monogamous.

    Now why on EARTH would I want to be with someone who claims to be monogamous butt hey go outside of that for the sexual experience? What kind of foolish person would I be to do that?
