What is cuckolding?
Cuckolding is a consensual practice in which a couple agrees that one partner will be intimate with someone else while the other partner, the cuckold or cuckquean, finds arousal or meaning in knowing or watching. It is negotiated in advance, often includes agreed power exchange, and either partner can stop at any time.

Cuckolding names the arrangement rather than the person. A couple agrees that one partner will have an experience with someone else, often a third person called a bull, while the other partner knows, agrees and takes part in the way they have chosen: watching, waiting nearby, or hearing about it later. Researchers also use the older word troilism for the same interest.
What usually separates it from the hotwife dynamic is the emotional frame. Hotwife couples tend to centre pride and celebration of the woman's desirability; cuckolding often includes agreed teasing, role play or power exchange, with the focus on the aware partner's own feelings. Neither is more valid, and couples choose the framing that fits them.
Because it can be emotionally charged, couples who practise it describe negotiating carefully beforehand: separating the fantasy from what they actually want to do, naming limits and any off-limits language, agreeing safer-sex and privacy rules, choosing a pause signal either partner can use, and planning aftercare and a check-in afterwards. Either partner can stop at any time, and an earlier yes never overrides a no now.
Published research is limited. A 2018 study in Archives of Sexual Behavior surveyed 580 predominantly gay-identified men and found that those who had acted on cuckolding fantasies tended to report positive experiences, with the likelihood depending on personality and attachment style. It is one sample, not a prediction for any couple.
