Boyfriend complains about not cumming twice

My boyfriend and I have sex (obviously), but every time we do, I always cum like 8 times the entire time and I try my best to get him to cum a couple of times but I fail to and he doesn’t tell me how I can. He complains all the time right after we do it and it makes me feel bad. He always says “I care once.” But I never get to do what I feel like I should do because he’s always the one to take over. Anyone have any ideas other than giving head?
