embarrassing question, but is this discharge normal?

So me and my boyfriend were making out for the first time last night, (my first time actually), and I started to get this discharge coming out of my vagina, like, the entire time. It was so bad I started to worry it would come through my jeans and get on him!

Its so embarrassing because it smells weird, kind of like cholorine. I went to a meeting immediately after and someone asked if I smelled chlorine! Of course I said no.

Is this normal? Is it just because I was getting, well, horny?
