Sex talk?👀

So you guys lately I’ve been having sex and after the sex I bleed very thinly but it last for maybe a few hours or a day. Is this normal or should I be worried? Like, I’m thinking it’s because my last 2 people I’ve had sex with dicks were actually big and I wasn’t exactly wet.. like foreplay wasn’t there so it made it a bit painful. Is this normal or should I go to the doctor? 👀
