Trying to him about his Oral sex

Ok my bf was the first guy to give me the big o it was good for a while i got one everytime but idk if its me or him but it's taking a while for me to get there sometimes i swear hes down theres forever, and now thats it's taking longer he's getting sloppy with it like hurry up nd cum already in his head. So he decided to turn the lights on to get a better view of my clit and out of frustration i said "2 years together and yu dont know where my clit is w/o light" and tbh turning the light on aint help, i tried to explain when he uses his mouth nd fingers me i enjoy it more. He got all pissed off saying he doesnt tell me how to give him head, and that he knows im faking and how if it doesn't feel good were going to atop. Like really were going to stop having sex insted of Yu taking pointers ...sorry for the rant
