Serious Questions from a Girl that just lost her virginity

Okay so last night I lost my virginity to one of my best friends. I've never experienced so much pain in my life. It hurt so bad that I made us stop. During it, discharge was dripping down my leg, and when he pulled out more came out. He had a condom on and he didn't even get to finish so it was all me.  Since then it's now been about a good 24 hours and the entire day my vagina had been sore on the inside, I've been discharging a LOT, and it smells. It doesn't smell like fish it just has a strong scent. What could this be from? Is it normal for your vagina to have a strong scent after sex? Is the discharge during and after normal? What could I do?
