Ddlg advice

My boyfriend told me he’s into ddlg and I’ve never experimented. I’ve only had sex a handful of times. I’m not only uncomfortable with the thought of participating in it but I also wouldn’t know what to do. I’m into experimenting if he gives me guidance but the few times we have had sex I initiated it. He likes to tease me. I’m just looking for advice because I don’t want him to get bored but I need guidance!!!
