While there are many variations in play exams, I see two basic styles; realistic and fantasy.
I prefer a realistic exam, where the examiner sticks basically to real medical protocol. Timing, body exposure are not realistic but most everything else is at least based on reality.
The other style is more fantastic. It might include restraint, pain and other non-medical techniques up to and including sex.
What's your preference? Please feel free to expound on your preference or style.
