Queenbull
The queenbull is the dominant partner in a cuckquean dynamic, a man who has sex with other women with his partner's full knowledge while maintaining the power position in the relationship. He is not simply someone having sex outside the relationship. He controls when, how, and whether his partner is involved or informed, and he does so as part of a deliberate power exchange. The role carries its own erotic charge: being actively desired by others while his partner accepts that position requires confidence and a specific kind of authority. Some queenbulls use humiliation explicitly; others maintain dominance through exclusion, comparison, or simple control of information.
HISTORY
"Queanbull" is a very recent coinage with no traceable history as a named identity. The role it describes, a man who sleeps with other women with his partner's knowledge and active encouragement, is ancient in practice, but the framing of it as a specific erotic position he consciously occupies belongs entirely to modern kink communities.
History is full of men who took other women with their wives present or aware. What is almost impossible to recover is whether those men understood themselves as performing a role for their partner's erotic benefit, as distinct from simply exercising the freedoms available to men of their class and era. The inner life of either party rarely made it into the record, and when it did, it was filtered through shame, discretion, or the assumption that a husband's other relationships were simply his business.
The men who come closest to something recognisable are those where the wife's active encouragement is documented rather than merely implied. H.G. Wells' wife Jane not only consented to his affairs but sent presents to his lovers and met them socially, which starts to look less like tolerance and more like facilitation. Whether Wells experienced that facilitation as erotic, whether her involvement in arranging his desire was part of what he wanted, is not recorded.
The queanbull as an identity, a man who specifically derives pleasure from being chosen, encouraged, or watched by his partner toward other women, requires the language of kink to exist at all. Before that language developed, what you had was a man with a wife who didn't stop him. Whether that dynamic carried an erotic charge for either of them is the thing history almost never preserved.
