I've never done dirty talk much but I'd like to with my next partner. Thinking about it now, I think a conversation up front is necessary. Because these words carry so many meanings. Others have discussed "daddy" already. "Pussy" comes to mind for me, "slut" too. If my partner and I know that we're using these words in certain ways (eg, "slut" is just about calling attention to someone's sexual needs and not misogyny or shaming), I think it could be a fun way to help each other's fantasies to the surface
