how to give better head??

okay ladies i need help lol. my boyfriend has always told me that he loves when i give him head & like he’s always like “that feels sooo good” but he never finishes. i’ve told him that he can finish in my mouth but he never lets me get that far, he always like pulls me off & is like “let’s have sex”. he says it’s because it turns him on a lot & makes him want to have sex, so i tried sucking his dick after we already had sex so maybe he’d be more likely to finish from that, & he just wants to go another round in bed lol. but i see these girls post on here about how their man is like moaning & squirming around & like their legs are shaking & stuff & my boyfriend doesn’t do any of that when i go down on him. how do you do that??😂 i wanna make him feel that good but i literally don’t know how lol
