They have done themselves in with the mainstream by having a title like that but oh well I get their sentiments. It does happen, and in fact a theory as to why women have the g-spot is to trigger an extra oxytocin release when the baby is descending down the birth canal to make sure baby is born. But so many women are having medical, drugged labours they wont be able to experience it. I have had a drug-free birth, and it did get intense but not as bad as on the drip and I would describe the experience as being on a huge high... I am not afraid of birth, I love it, can't wait to experience it again when I am ready.
