ELI5: Explain Like I'm 5

Collar (BDSM)

A collar is something people in the BDSM community use to help them feel like they are in control or in charge. It's like a special symbol that the person wearing it and the person they are with both agree they can trust. It can be worn around the neck and often has symbols of love and devotion. It's a reminder to both people that they are in a relationship that is more than just sexual, but is about trust, respect, and understanding too.
