Losing my virginity!

So I lost my virginity just yesterday to my boyfriend, and it hurt a bit so we only did it in one position, and he didn't ejaculate cause he was so nervous of cumming inside me (yes it was without a condom), so it was just like a 10 minute thing. During the sex though, I felt like this liquid in my vagina and it felt weird cause it was like his penis was hitting against it and I would feel it. Is that normal? What was that liquid?
