i have to agree with remaining professional but at the same time if you are going to wear this at work you can't be surprised if people ask questions. Wearing collars or chokers in a professional situation is going to raise questions and in your case it may not only be with co-workers but eventualy patients. Heck wearing slave appareal in public is going to raise questions or at least stares. What you need to ask yourself is is it worth wearing the choker at work and raising suspicions. By not answering questions, which is probably the right thing to do, you are inviting rumors to start and people to draw their own conclusions. People make snap judgments all the time, unfortunatly. I'm not saying not to wear your choker but maybe not at work or find something to wear that's not so BDSM like an anklet that isn't really noticed. You still know it's there and what it stands for but others don't.
