I don't see why it necessarily has to be traumatizing.
I know there's a good chance you're high so let's get this straight.
A doctor will have to cut you up. There's only 2 reasons for a doctor to go along. The first is unhealthy levels of sadism. The second is an acute need for money. No one in their right mind would go along with this. And generally cutting up a person that's alive would be traumatizing to everyone. Just look up stories of doctors in warzones. Seeing this stuff can cause bad defense mechanisms to activate through our innate instincts and most doctors have mad PTSD if they deal with this a few times. Cutting someone up that's alive is like that, but tuned to an extreme that even less people can bear.
