You WILL have a vaginal delivery, unless there are clear medical reasons to have a c-section. It isn't something you usually get to choose.
And, if you do get to choose -- I would take a vaginal delivery. Vaginal delivery hurts -- but you have many options for pain relief if you need them. And, once baby has arrived, the pain is over. C-section doesn't hurt during the operation (you get, basically the same pain relief you'd get for a medicated vaginal delivery), but then you have several weeks/months of post-op pain. And, not only are you in pain, but you are caring for a newborn, establishing breastfeeding, entertaining company, doing the usual housework, etc.
