Who wants the additional-partner seat in cuckolding?
The additional-partner seat was uncommon across role groups and least popular with submissive-identifying Cuckolding quiz takers.
Very few Cuckolding quiz takers wanted to be the additional partner, the person invited into an existing couple's fantasy. Submissive-identifying takers chose that seat least often. Dominant-identifying takers chose it more often, although it remained uncommon for them too.
Being the additional partner is a different desire from watching your own partner with somebody else. It is not a more advanced version of watching, and it is not automatically the dominant position in the scene.

No role on file 12.3%. Dominant-identifying 9.6%. Dominant- and submissive-identifying 5.2%. Submissive-identifying 2.5%.
These answers describe an imagined seat in the fantasy, not a history of what anyone has done or plans to do with another couple. Desire and biography are different questions.
Wanting to join a couple is a fantasy of its own
A familiar cuckolding setup starts inside the couple. One partner has sex with somebody else; the other knows, watches or hears about it. The additional partner is the somebody else. They enter a fantasy shaped by a relationship that already has its own history and erotic charge.
A person can want this seat without identifying as a cuckold. This person joins another couple's fantasy from outside its established relationship. Someone may enjoy being desired by a couple or becoming the focus of a fantasy the couple has built together. They might take charge, follow the couple's lead or play without any hierarchy at all. "Additional partner" tells us where someone sits in the arrangement. It tells us nothing about who holds power once the sex starts. Position in the arrangement and authority within it are separate choices.
From that outside position, they are not simply observing a couple's desire. Their presence creates the encounter the couple is responding to. They can enjoy being the catalyst without wanting either established partner's place.
Dominant-identifying people chose this position more often than submissive-identifying takers. It remained uncommon in every role group.
"No role on file" means a taker had not saved a dominant or submissive identity on their profile. It is not a fourth BDSM role.
Wanting to watch your partner is different from wanting to join another couple
The question "Do cuckolds want to do more than watch?" turns the watcher into someone who has not yet worked up to the real action. These fantasies do not follow that ladder.
Watching can be the centre of the scene. A person may want the ache of seeing their partner desired, the humiliation of being kept at a distance, the authority of deciding what happens or the pleasure of welcoming their partner back afterwards. None is an incomplete version of becoming the additional partner. They are different erotic positions.
The additional partner is not being promoted from the audience. They are participating in the encounter rather than watching their own partner from within the established relationship. Even when everyone shares a room, their perspective differs from that of the established partner watching.
In Justin Lehmiller, David Ley and Dan Savage's study, cuckolding fantasies overlapped with voyeuristic and group-sex interests, and their content varied. Watching and joining can live in the same broad fantasy family without being steps towards the same destination.
Being dominant or submissive does not tell us whether someone wants to watch or join in
Dominant and submissive describe someone's relationship with erotic authority. They do not decide whether that person wants to be inside the couple, outside it, watching or having the sex being watched.
A dominant-identifying person might imagine joining a couple and taking charge. They might be equally excited by entering a scene where the couple sets every condition. A submissive-identifying person could want to serve both partners, become the focus of their attention or avoid this position entirely. The arrangement creates possibilities; it does not assign the power.
The same is true inside the established couple. A submissive-identifying partner might organise the encounter. A dominant-identifying partner might want to watch without directing a thing. A person's profile role does not dictate where they sit in a particular fantasy.
Submissive-identifying takers were especially unlikely to picture themselves as the person joining somebody else's dynamic. That preference belongs to this particular seat. The same person may still want the fantasy intensely from inside the established couple.
Treating watching, joining and taking charge as stages of one journey muddles the language. They are separate parts in the scene. Naming who belongs to the established couple, who is being invited in and where authority sits makes each person's desire specific. The additional partner is not the person who went furthest. They wanted a different part.
