What does the noun and adverb "Cuckold" refer to? Unlike the traditional definition of the term, in fetish usage a cuckold is complicit in their partner's sexual "infidelity" and takes masochistic sexual pleasure in it. Cuckolds in the fetish sense also need not be male, and need not be married, although some level of pair-bonding intimacy or commitment in their relationship is necessary.
Among fetishists, the pose of reluctance—the victimization of the cuckold—is a major element of the paraphilia. (Which may be the reason for the use of the term "cuckold," with its connotations of victimization and inadequacy.) In the alternative lifestyle community and the fetish cuckolding subculture, it is most common for the female to take on the sexually dominant role and the male the submissive role, however, female subs, sometimes referred to as cuckqueans, also exist.
The wife who enjoys cuckolding her husband is frequently called a "hotwife," or a "cuckoldress" if the man is more submissive. Fetish cuckolding can have a wide range of expression, from pillow-talk fantasy between monogamous partners to extreme "alternative lifestyles," depending on the couple. It is also often mixed with other fetishes in practice, such as voyeurism, denial, etc.
Cuckolding can also be mixed with other non-monogamous relationship arrangements with which it has substantial overlap such as Swinging, wife-swapping, open relationships, and polyamory, etc. It is distinguished from these concepts in that the cuckold's thrill in their partner's acts is specifically masochistic; as such it is considered a category of BDSM fetish.
