What Causes Splitting Up Of Clitoris Leading To Painful Intercourse?

my wife went to the doctor to see why her clitoritis is splitting, which causes her pain during sex. and she was told it is becouse she is dry. So we did not have sex for 2 weeks to let it heal, and when we did have sex we used KY gel, well need less to say it has never fully healed and seams to come and go. We were wondering is there something else going on
