Daddy kink? Advice?

My husband and I have mentioned before how cringey the daddy kink is (not judging those who do it, just for us, we couldn't get past the father/daughter thought with the word daddy).

Anyways. I think I might be into it? I've been reading a lot of smutty books lately and I love when she'll call him daddy in the bedroom. I want to try it, but I don't know how to go about initiating it. There's been times in the bedroom where I felt the urge to say it and it almost just came out, but held it in because I don't want to ruin the moment for him if he's not into it.

I'm so awkward when it comes to dirty talk or talking to him about my wants like this. Like I said, he's talked about it before how he thinks it's weird/gross for someone to call their husband "daddy", so I feel like I already know the answer and it would be pointless to bring it up and just make things a little weird.

Also, I do have actual daddy issues, so that makes me feel even more weird about it. Like, I'm not wanting that father/daughter aspect of using the word daddy. Just the dominant side of it, if that makes sense?
