Marriage & sex

What can I do to better my sex life with my husband? Lastnight I felt as if he didn’t even want to have sex and only did because I said something. Idk if it’s bc I did most the work. Started it off I was in top etc. we’ve struggled in the past & he mentioned how we barely have sex & that was an issue for him & I agree. We spoke on things & we were better for a little bit but now it seems like he can go days without even wanting to or won’t say anything. He’s told me to just whip it & get to it whenever I want. Buttttt idk why I feel awkward about that stuff. 😂💀 send help. How can I get over that awkwardness 🥲 I know it’s normal to have sex and please each other but ugh.
