Painful bleeding sex

Hello,

I rarely post anything but this time I feel it's important.

I'm 20 and I hadn't have sex in more than 8 months. Today, I had sex with my new partner. However, he was a little bit rough. It was painful and when we finish, I realized I was bleeding. I'm not in period so it wasn't menstruation blood.

Is it normal to bleed after sex? Should I be worried about it?
