You are not alone. In 1959 or 60 I went to a senior managers dinner given by my employers at what at that time was the most prestigious hotel in the North of England. The main course was Beef Tournedos and as I looked around the room I noticed that most of the 80 or so guests, themajority were carefully cutting off the cooked sides of the cubes of beef and discarding the uncooked centre.
When I commented on what I had seen, our Chief Chemist invited me to his laboratory where he prepared a microscope slide with a section of the discarded meat. It was absolutely crawling with the most terrifying creatures that I have ever seen. I have refused to eat "rare" meat ever since.
I have also noticed since then that whenever I have suffered with digestive disorders it almost invariably is traced back to eating uncooked food,
