Sex AFTER birth. Sorry if it is TMI

Hi guys.. I just had a couple questions I hope you guys could help and answer for me. I know this might be a bit TMI, but I just want to know how sex was for you and your SO after birth? I’ve had a couple of my girl friends tell me that it’s painful the first couple times and then it’s fine afterwards. And I have a friend who’s baby is a YEAR old and she was telling me that she still to this day cannot do doggy style because of the pain. Curiosity killed the cat but I am dying to know 😜😜
