I don’t think there is any chance of a man conceding ever that women may actually experience excruciating pain. I have to admit however that the pinched sciatic nerve that has left permanent damage in my right foot was worse than any pain of childbirth. It was indescribable and i night have been tempted to agree to being shot if I had even been able to hear anything about the level of pain. And I know I have a high pain threshold.
I think men believe that because women have more than one child somehow the pain must be bearable. Ignoring of course the use of painkillers that sometimes only barely dull it. I think it is the miracle of nature and body chemistry myself.
