Getting Too Wet?

So my boyfriend and I have had sex twice today. One time I was on top, the other he was on top. I normally get wet, but not this wet. I left a puddle on the bed... I'm talking huge puddle and it was pretty much dripping. It was super messy and my boyfriend got it all over his bottom half. It made for good lube and fun sex but now I'm kind of worried. I've never been this wet during sex. He said it smelled kind of like pee although I know for a fact it wasn't. Could I have an infection? Is this normal? Should I be worried?
