giving him head

last week i sucked my boyfriends dick for the first time and i was doing it for 2 hours and nothing. he didn’t cum but he was hard and everything... i barely used my hands and went all out to the point where i couldn’t breathe because i kept deep throating the whole time... he kept whispering under his breathe “oh my God” and softly moaning but HE DIDNT CUM!! WHAT WAS I DOING WRONG... afterwards when i had left... he texted me that i give the best head ever hands down... but. he. didn’t. cum. i even sucked his balls to maybe wake up his sperm or something .-. the next day i woke up with the worst sore throat ever. HOW DO I MAKE HIM CUM !!?? i’m giving him head tomorrow please help. i just want him to feel the way he makes me feel!!
