Well, like I sad, it's worth exploring. Too often, the whole "Is childbirth the worst thing you've ever experienced?" question tends to get thrown around without any real purpose. Sometimes people say it to fake empathy, sometimes its posited as a way of justifying men as boxing women into a gender role (i.e. It was painful? That just shows how important your role as baby machine is.) The question itself can be well meaning, but it still has profound psychological components that need to be explored. In essence, it's not a question that you might have greater intent, but it is preloaded with those grand comparisons.
