Parallel polyamory

What is parallel polyamory?

Parallel polyamory is the polyamorous style in which someone’s relationships deliberately run side by side without touching. The metamours, your partner’s partners, have little to no contact and need not know one another. The image that goes with it is that of two rails: heading the same way, but never together at one point.

What parallel polyamory looks like in practice

Parallel polyamory shows up in two calendars that almost never cross. Take a woman with two partners who both know the other exists, but who have no interest in getting coffee together and don’t. She sees one partner on Tuesday, the other at the weekend, and the two men meet at most once a year by chance. Polyamory writer Minka describes it this way: metamours have little to no contact, their relationships run at the same time but never intersect, like a railway with two rails. Everyone knows of the other’s existence; they just don’t share the same space. In practice that often means separate friend groups, separate holidays, and separate birthdays, with the shared partner as the only link between the two worlds.

How parallel polyamory works

The engine under parallel polyamory is separation by design, not by accident. Each relationship has its own rhythm, its own arrangements, and its own privacy, and the pivot figure who shares both partners keeps information between the relationships largely to themselves. That calls for clear arrangements about what you do and do not pass on. Some couples go a step further and agree don’t ask, don’t tell: they don’t mention the other relationship at all. Parallel polyamory need not be that strict. The difference is in the intention: the relationships run apart because those involved find that pleasant, not because something is hidden. Consensual non-monogamy is by now a seriously studied field: the scoping review by Gupta, Tarantino, and Sanner brought together 209 studies and shows there is not one right form, but a spectrum of ways people arrange this.

Why people choose parallel polyamory

The appeal is in calm and autonomy. Anyone who keeps their relationships apart does not have to keep comparing them and can be fully present with each partner without the other in mind. For you that can mean a new relationship gets to grow without a whole network of expectations hanging off it straight away. For a partner who is introverted, or who simply has no need for friendship with a metamour, it takes away a social pressure that does play into other poly styles. Against that there is a price. Less contact also means less sight of each other, and a metamour who feels left out can start to feel lonely in the whole. Parallel polyamory works best when everyone really wants the distance, not when one person merely puts up with it. That is exactly why it is good to check now and then whether the separate setup still fits everyone, instead of assuming that silence is consent.

What parallel polyamory is not

“Parallel polyamory is secretive, so really cheating.” No. Everyone knows of the other’s existence and has consented; only the interaction between the metamours is missing. With cheating it is precisely the consent that is missing.

“It’s the unhealthy variant of polyamory.” Parallel polyamory often gets that label, but it is a valid preference as soon as both metamours want the distance. Separate relationships are no less serious than interwoven ones.

“Without contact between metamours no trust is needed.” The opposite. Precisely because you don’t see each other, parallel polyamory leans heavily on trust in the shared partner and on clear arrangements about time and safety.

What you can arrange yourself

Parallel polyamory runs more smoothly with a few arrangements beforehand.

• Decide together what you do and do not pass on. Agree how much each partner hears about the other relationship, so no one is caught off guard later about what was or was not shared.
• Arrange safer sex across the relationships. Because the relationships run separately, the coordination about testing and protection rests with the shared partner. Make concrete arrangements about that, because your metamour is not in the same conversation.
• Choose a rhythm that fits, not one that happens to be left over. Divide your time deliberately across your partners instead of giving one relationship the leftovers of the other.
• Don’t use the distance to dodge a difficult conversation. The mistake beginners make is using parallel polyamory as a place to hide tension. It is a preference for separate relationships, not a hiding place for what you would rather not discuss.
