M4F 30 - White male want to introduced more raceplay with my black gf

I've been with my gf for 3 years now, and we're really happy. She is more liberal/left and I am more conservative. I started introducing a little raceplay last year.

Nothing degrading but during sex telling her how much I love her black pussy, and my telling her to take my BWC.

She said at first she was a bit surprised (I am the first white guys she's been with), but now she enjoys it, and says similar stuff back to me.

My questions is, mainly to black girls out there, how do I introduce more raceplay, like slurs. She obviously hates the N word in real life, so I feel like if we are going to use it in the bedroom, she needs to be the one to use it first, so it shows me I can use it. Or shall I just come out with it and hope for the best.

Any black ladies out there have any advice?
