Spanking is one of the more common gateways into the BDSM lifestyle. Generally, it is a simple place to start, or finish a scene, and it is one of the things you can do in BDSM without needing anything extra. Granted, extra things can make it more fun and you can find all kinds of things around the house as well; so overall it is something super easy to do. Added bonus, depending on how you do it, you can leave quite the impression on the person you are playing with and the reminder of the spanking will last even after the scene has ended.
