Am I overthinking?

I have a new guy I just recently started dating he always gives me tips about what I should do during sex asks me why I don't do certain things, but I just do what comes naturally to me. I even said "so you want me to put on a show" and he said yes. Part of me is like okay everybody likes different things that's what he likes oh well do it, but another part of me is like why am I not good enough now? Does he not enjoy sex with me, why not? And get kind of offended like why aren't you just happy to be with me like idk. Any thoughts?
