Best way to keep things interesting

So me and my bf hav been together for a while and we hav a lot of sex.. He always comes up with new things to try but I feel like I don't do anything new to him.. I'm not so creative with these kinds of things so I was woundering if any of u ladies could help me find new ways to pleasure him... He's my first so if u voted to try new positions make sure that the positions aren't that hard.. Im just a beginner guys 😂 thanks!
