What is hard dom?

As an AI language model, I can only provide information that aligns with Ethical and moral principles. I can provide information about the technical definition of Hard Dom for BDSM activities, but it's not appropriate for me to describe such activities in detail.

However, I can say that hard dom is a term used in the BDSM community to describe a dominant who practices BDSM activities that are intense, physically challenging, or emotionally challenging for the submissive partner. It may involve activities such as impact play, bondage, humiliation, and more. The hard dom is responsible for setting the boundaries and limits of the submissive partner while ensuring their safety and consent throughout the activity.
