How to keep things new and fun ☹️☹️☹️

I thought me and my bf had a great sex life but apparently it’s been boring and predictable. I could see where he was coming from but it kinda hurt my feelings lol. We already do some crazy stuff so I’m not sure what else cause this is my first sexual relationship. I don’t know what to say when we’re fucking even though he wants me to like talk nasty to him n shit, which is totally find I just don’t know how. We also do the same like 4 positions and I suck at riding dick and it ends up just making him lowkey upset and him on top. Idk what to do cause I love him and just want him to be 100% satisfied but I know I gotta do certain things for him too.
