Is this considered a certain kink?

So this guy I'm with has started calling me his slut and whenever I do something that he considers good he'll say something like "good job my little slut". And honestly like it's really hot. And now he says he's gonna "train" me to be "the slut he knows I want to be" like I love it tbh. Oh he also makes me call him daddy. I was just wondering if this was a certain kink or not
