Things to try, I’m still too new lol

Ladies! I need some help thinking of things to try with my SO we’ve been together a little over two years, we do have two kids (eldest is mine from a crazy long time ago). I’m only 23 and he’s the second guy I’ve been with, so we both are used to just plain boring sex and we’ve been trying new positions and things. For example we just started using toys, this is my first time ever with this stuff lol. I’m just looking for ideas, I do like when he gets rough with me just not sure how rough yet. We’ve got great communication which I’m thankful for, if I’m uncomfortable or need him to stop he listens and stops right then
