Dirty talk during sex

Hiiiiii

So I need y’all advise on talking/ saying dirty things during sex. What are some sexy things I could say? Whenever my boyfriend says stuff it’s like I freeze up and don’t know what to say back. Even the simplest things that he says like “you’re so sexy” how can I respond back to that without being awkward???

Pleaseeeee if anyone has any advice at all help ya girl out because she is struggling 😭
