Male ejaculation help

So, my bf and I were making out. He was on top, and I started giving him a hand job. I know his head is super sensitive, so of course I focused on that because I wanted him to cum. When he gets close, he says “I’m gonna squirt.” I tell him that’s okay. However, when he does it, a lot of fluid comes out. I mean A LOT. I was WET. Apparently it wasn’t cum. He told me that happens when there’s a lot of focus on his head, and when he masturbates, he focuses on the shaft so that doesn’t happen. I have never experienced this before and asked him about it, but he had no idea what it was either. My immediate thought was that he peed on me, but it didn’t look or smell like that.

Just wondering if anyone else has experienced this with their bf or knows anything about this. I don’t even know what to look up on google to find answers.
