Polysaturated
Having as many partners as your time, energy, and emotional capacity can support — not open to forming additional connections at present.
Polysaturated describes a polyamorous person who is at their current capacity for partnerships. They are not seeking additional partners not because they have closed the relationship structure, but because they cannot — in good faith — take on another connection without undermining the ones they already have. The polysaturation state is honest about a real limit: time, sleep, attention, emotional capacity, money for dates and travel, the ability to show up in a crisis.
Polysaturation is not a fixed state. Capacity changes with circumstances. A partner moving away, a long-running relationship transitioning to less time-intensive, or a year of professional stability after a chaotic one can shift the saturation point. People sometimes describe being polysaturated for years, then having space again.
The opposite term, polyamorous-but-not-currently-saturated, is sometimes shortened to 'poly with capacity.' On dating profiles, an explicit note about whether the writer is at capacity or has openness for new connections is more useful than a binary identity label.
Polysaturation is also a signal of mature practice. Earlier-career polyamorous practitioners sometimes over-extend, take on too many connections, and learn the hard way that being polyamorous in orientation does not mean having infinite capacity in practice. Acknowledging the limit out loud is part of doing the practice well.
