The birth of my daughter was the most spiritually uplifting event I have ever witnessed. Apart from peeling an onion or seeing your team relegated from the Premiership, nothing is guaranteed to bring a tear from even the most hardened macho cynic than the birth of a child. Over the years, it has become increasingly voguish for men to be present in the delivery room, but for all the awe and magic of childbirth, the sight of a sweating, hyperventilating, haemorrhaging woman, in the midst of thrusting 10lbs of living, breathing tissue through her body, non-stop for eight hours, can have a lasting effect on your libido.
