Does it hurt after you finish?

So this guy I'm fucking has a hard time doing two rounds because he said after he cums his dick hurts. When I'm sucking his dick I like to keep going after he cumz in my mouth but he has to RIP my face off and cover up his dick to get me to stop. today he was at. my house and I gave him head 2 and then we fucked once. i had to start it all 3 times. But I just want to ask the guys out here is this a common problem ir how can I help him? I was thinking we need to have sex more often and frequently to make it go away. I want to habe non stop sex. How can I make this problem go away?
