I squirted too much the last time i got fingered, is it normal?

The last time my bf fingered me we hadn't had sex for a while and he was being pretty rough and I think I squirted (sometimes I do). However it was a huge amount and I soaked my skirt, and his car seat. I thought it was really weird that it was that much and that perhaps it had to do with the roughness but he said not to worry that it was just squirt. I am really worried that it was pee instead, because it did smell like pee, however when I went to the bathroom I peed quite a lot so it couldn't have been that, could it? It started when I was coming and then it stopped but I soaked everything and I'm really embarrassed about it. What if it was pee?? It did smell like it and I am concerned it might happen again, I'd die!! Is it normal to squirt this much??
