Sex after baby ...

Deanna • Im a FTM to a baby girl born April 29 (after being told i could not have children) i plan to stay at home with her :) and im pro breastfeeding!
Why do i see all these posts about women asking if they can have sex before the 6 week cut off...? Like one i dont even thing of my body in a sexual way anymore lol and two your dr said 6 weeks why would that change...its said for a reason thats how people get pregnant with another baby unexpectedly i had a Csection fyi so im too tender to even roll over
