Can't feel when he cums?

First time I had sex with the guy I'm seeing now, I was on top and after awhile he said "I don't wanna cum inside you" so I got off, and literally half a second later he came. A lot. And at first I was kinda thinking dang, could've given me more notice. 😂 Like he could've straight up said I'm about to cum, instead of I don't wanna cum inside of you. Come to find out, he had NO idea he was about to cum. Like he felt like he was close, but not THAT close. He said that's the first time it's ever happened to him. And he was still hard after that/ready for round 2. Anyone else's man like that? I know not all guys can feel when they precum, but this was a full-blown orgasm. Never experienced this before.
