I understand you like fetishes and kink, which is fine, so I imagine that you may like role-play, which is certainly great, too, and if you like PLAYING the role of a ***** and DRESSING like a *****, as in a GAME, this is totally OK and wonderful, but you should never have words such as "*****, slut" in your SERIOUS vocabulary. It should belong to role-play only. If you do not use racial slurs when talking about other people and I assume that you don't, you should not refer to yourself using derogatory terms.
