Confused!

My boyfriend and I have been dating for about two years and I just told him about my kink a few months ago. I have always been very into DDLG, both sexually and non sexually (I find it very comforting) He’s a switch, but loves to be dominated as much as I do. We were stuck thinking how we could both incorporate our needs. We agreed that I act how little I want, but brattier and more confident- act like I’m in charge (but in reality daddy is in charge) I’ve been trying to become more confident and comfortable with calling him daddy and act confident during sex but I get so nervous. I get shy! Lol I go through period of times where I get so embarrassed that I don’t call him daddy for weeks, and I know it frustrates him as well.

How can I become more confident in myself and express that to him?

I hope that one day we can form a natural ddlg dynamic in everyday life
