Spicing up vanilla bedroom tips pls

Hey brains trust, I'm looking for some ideas on something to do to spice things up in the bedroom. I'm a very submissive person in bed and partner has mentioned he wants me to come up with some ideas of things to try. I've looked on like every blog full of ideas and I JUST DONT KNOW I feel like everything that interests me we've already tried. Anything else he seems to be uncomfortable with (eg I'm into choking, being held down, hair pulling etc) and told him this and he feels uncomfortable doing it. Also tips on how to work on this would be great haha. But looking for some suggestions that aren't just "do role play," "take charge" and looking for some specific tips on things to try, specifically things to do to him. Thanks 🤞
