We had sex for the first time post baby last night - I've wanted to for weeks, but been too busy, so I was well up for it! Imagine my surprise then at feeling very sore/dry down there! i had a cs so as far as i know, no birth-related fanjo trauma? This has never happened for me before, I'm usually extremely wet at the drop of a hat (TMI sorry!) 
Could it be a side effect of demand BFing?
