I haven`t had an emergency c/sec but I have had 2 c/secs and both times it hurt DTD, even after using lots of lube, I just found out 2 weeks ago as to why it was so uncomfortable, apparently when BFing we go into a menopausal state and our estrogen drops away, so my OB prescribed oestrogen cream, I`ve only used it twice then stopped and no more pain.
