Subject/Subject Consciousness, is a concept developed by Harry Hay, the founder of the Radical Faeries. This is to a style of relationship of mutual respect and empathy for the other. Subject/Object dynamics are between people where the one in power, dehumanizes objectectifies and treats the other as subordinate. We sometimes play with the latter erotically. When objectifying a submissive, bottom or slave, remember, you are doing that to have a hot scene. That power exchange is to rock each others world. Thats done with mutual respect for the well being of the other.
