Painful Sex TMI

I'm 6 months pp and sex has recently become painful for me. We had sex before, and it wasn't as painful as it now. It was uncomfortable at first but not when we try it feels like I'm too tight for there and I have to stop seconds in because it hurts too much. My sex drive has been so low as well but it may have something to do with knowing how painful sex is for me. I had my son via C-section. Is this normal? Does it go away eventually? I'm just waiting to feel normal again.
