My significant other isn't into the lifestyle, even as a hobby, so neither of us are collared. I do, however, wear a belled collar sometimes when I go clubbing or something to that extent. It's more fashion than symbolic

Once though, a few weeks ago, we were at an adult superstore while I was wearing one and he got tired of my constant running around from item to item ogling or reading the package in a loud voice, so he pulled a lanyard from his pant pocket and attached it to my collar. He led me around by it and it was quite fun! That story had nothing to do with anything, by the way, it's just a rather fond memory that I like sharing
