I recommend you get your hands on the excellent book about caesareans called "Delivery by Appointment". It goes through all the sorts of things that can go wrong and the type of impact it can have. The author is pro-VB but has written a very well researched and balanced book that anyone making this decision should read.

My CS experience was a very positive and empowered one however I did have problems with wound infection for a couple of months afterwards - definitely meant i was in more pain than usual and for longer than normal. However for all of that I'm still very happy with what I chose.
