I made these practices for couples who want to explore attention, initiative and response without turning the evening into a performance. You need privacy, enough time not to rush, a long scarf or soft length of fabric, and a clear agreement that either of you can pause or stop.
Here, polarity means a contrast you choose to explore between initiating and responding, leading and following, holding and being held. It is not a claim about gender, and it is not a rule about how either partner should behave.
