how do i spice things up in bed?

So yeah, I (22M) met a girl (20F) like a year ago and things are going fantastic, i really love her and so do her, we are very passionate and get intimate very often (like once or twice a week) we found out thats kinda our love language, anyways, we both are sort of shy in some aspects of it, and I want to be the first of us that try to bring something new to those intimate moments but i dont know what and how to do it, I know she wont say no because we trust each other so much, and i want it to be so romantic cause she loves it and we are yet to discover what are our favorite things to do. (sorry if my english is bad or something, learning english it’s actually a thing im doing to surprise her) Do yall have any recommendations on how to start doing that? 🤓
