I'm not sure why people would opt for a cs if there is no medical reason too, I know some stars have cs " too posh to push" or fear doing damage down there.
For me I would not select to have major surgery if there is no reason to. Even after a 33hr longstressful horrible labour with ds1, it didn't make me feel like I wanted a cs next time and i didn't. My second labour was a breeze, 4hrs. And although I had 2 episiotomies everything went bavk to normal down there and i don't have any scarring.
