I think I squirted

So me boyfriend and I were messing around. He was rubbing my clit. I mean it was good but not super special. But I guess the orgasm was a lot because supposedly I squirted. I kinda felt a release but I didn’t realize until he said I squirted. What is it though. I’ve heard that it’s pee. Some say it is lady juices. I mean it looked thicker so I’m thing lady juices? But where does it come from?
