Childbirth is one of the most painful things anyone can ever go through. It's something that only half of the population can do, and something a lot of people end up doing more than once.
Anyone who's had a baby knows what it feels like. But anyone who hasn't (whether they never will, or plan on giving birth someday) definitely won't. So the descriptions of childbirth from these Reddit users are definitely informative, even if they are terrifying.
