Bf says he does all the sex work?

I’m 17 and my bf is 19. My bf has said a few times now that I just lay there and take dick and that he’s the one doing all the work (which I find insulting). Mean while I’m the one who does most of the foreplay and gives him bjs. He doesn’t even like to eat me out. I don’t understand what I’m supposed to do? I’ve down cow girl style on him before but its not even our best position. Like I don’t have a dick it’s not like I can do missionary on him idk what he expects here??? Help me
