My boyfriend stopped giving me head and just looked at me, what does this mean?

So earlier this week my boyfriend was giving me head when he just stopped and looked up at me awkwardly smiling. I just smiled back because i wasn’t sure what he was expecting me to do or say. After like 10 seconds of that he came back and we started kissing again. It was a strange moment and i wasn’t sure if i did something wrong. But feels far too weird to ask now. Any ideas what might have happened?
