V -jay question

Haven't gotten a pap test in a while. Been wanting but it's always one thing or another.

My hubby saids that after having my baby (had him csection)....its as if my vjay got hostile. Almost 2 yrs ago. My libido is there but his its not because he saids that his penis get a lil sore and feels like tiny razor cuts after we had sex. Due to that we had arguments about sex. Til he told that he's afraid of my vjay cause although it gets a little better- he still feels as my vagina have teeth.

So what is this teeth like things that I have?
