Advice for new to ddlg? (I’m 18)

hey guys

So I’m new to all of this (recently turned 18) I’ve always been into this kind of thing but just kinda kept it to myself because I didn’t really know what it meant yknow? Well me and my boyfriend have been together for a while now and I’m not really sure how to tell him

He likes when I call him daddy in bed but I’ve never called him that other than in bed

Recently I’ve kinda sorta accidentally gotten into little space around him? Kinda?

Like my voice changes and I’ll say things differently, and I’ll cuddle with stuffies and stuff like that , and he always thinks it’s really adorable, but I’m just not sure if he’d be into ddlg completely and I don’t want to ruin our relationship..

idk I just don’t really know how to talk to him about it 🙊 help??
