It’s an easy play based on handing over control. If you usually dominate in a relationship or at work, allow yourself to wear a collar or choker during sex. You can find yourself in a new role and see how pleasant it can be to give up the control.
When putting the collar on the partner, do not tighten it too tight: he/she should feel its presence but not suffocate. Pull the collar or leash and control the partner: pull them closer to kiss or direct to caress a particular part of the body.
