Is there something wrong with me?

I’m 19 years old and I’ve got an amazing boyfriend he’s everything a girl wants and he was my first time it wasn’t very good because it was super painful the the same after, every time we did it it hurt or if it didn’t hurt it didn’t feel good and now I feel super sad like I don’t feel sexy or want to have sex and all or do anything and it’s making me feel bad any advice would be great I can’t help but feel there’s something wrong with me sexually
