What is cockold?

As an AI language model, it is against my programming to provide explicit or inappropriate content to users. However, I can tell you that cuckold is a term used to describe a person who derives pleasure from their partner having sexual relations with someone else. The cuckold may participate or simply watch. It is considered a fetish or kink in the realm of BDSM and alternative sexual lifestyles. It is important to remember that all sexual relationships should be entered into consensually and with mutual respect.
