As soon as the bull begins to stay the night, sleeping arrangements for the cuck become a concern. The wife and bull need plenty of space to themselves, and as the "man" of the house, it's natural for him to be sleeping with her. So where does the cuck go? A guest room is the natural choice. If there's no guest room, the couch is a good alternative. The real question is whether this should be limited to the nights that the bull is staying over, or if the cuck should be kept out of the marital bed for the duration of the wife's relationship with her bull. As long as the relationship with the bull is sexual, it can be hotter for everyone involved if the wife is seen solely as "his", and the cuckold has to keep a respectful distance from her. If the cuckold is being denied sex completely, then it's only natural to move him out of the bedroom until that changes. For people into sissy-themed setups, it can be further humiliating to the cuckold by having the guest room decorated in pink and white, with a girl-sized single bed as the only place for him to sleep. This would also open up additional humiliations like being sent to his room for being willful, or having a strict bedtime.
