Sex hurts the second time?!

I’m not sure if this is just me or not, I’m hoping not! But I have a problem, if I have sex already in one day, it hurts later. It hurts so badly even if we are really gentle and slow! Every single time he moves or anything inside me it feels like sandpaper. I don’t have a problem getting wet again, but it doesn’t feel that way when he’s inside me. It’s like a friction/sore feeling. Am I just sensitive or does anyone else have this problem???
