Polyamorous and ENM relationships involve a lot of communication. Lykewise does not replace that communication, but it can make some conversations easier to start.
Here are a few ways people in poly and ENM dynamics use it.
Checking in with existing partners. You have been together for a while and you are curious about trying something new -- a different dynamic, a type of play you have not explored, or a shift in your relationship structure. Instead of putting someone on the spot, create a question set. If there is mutual interest, great -- now you have a starting point. If not, nobody had to say no to someone's face.
Exploring a new connection. Someone new has been spending time with your group. There is a spark, but you are not sure if it is mutual. Rather than guessing or asking around, add them to a set. The mutual approval gate means nothing happens unless both of you want it to.
Group dynamics. If you are part of a polycule or a broader network, you can create separate sets with different people to understand where interests align. Each set is independent -- the people in one set cannot see anything about another.
Navigating the kitchen table. In kitchen table poly, metamours interact directly. Lykewise can help figure out what kind of relationship metamours are interested in having with each other -- purely platonic, friendly, or something more. Use the connection and romance lists to find out without making assumptions.
One thing worth noting: Lykewise shows you what someone is interested in, not what they are available for. A mutual yes on a question means you both have that interest -- but logistics, existing agreements, and boundaries are still conversations you need to have. Think of Lykewise as the "is there mutual interest?" step, not the "let us make a plan" step.
The identity code system works well for poly networks. Share your code once and anyone in your circle can use it. You control everything on your end -- when to answer, whether to approve, and whether to block.
