Boyfriend was getting mad when I couldn’t make him cum?

So guys, this has never happened before. But me and my boyfriend started having sex and he got soft like halfway through. So he then asked if I could just like give him oral to make him cum and I was doing like everything I could but it took like almost an hour and a half and he kept getting so mad at me because he kept getting soft and he was like “what the fuck are you doing” and like “why did you stop” and things like that... I like didn’t want to continue but he told me to keep going and stuff. is this normal
