In a real life situation, I prefer a doctor who gives me a clear message:
This is what is wrong with you and here's how I am going to fix it. The get into the act of fixing my ailment.
No scope for discussion or negotiation.
In a play-doctor situation:
If I was a patient, I would like a doctor who would empathize with me, fuss over me, cajole me into her treatment, by coaxing me - but just once.
If her coaxing does not work, then I would expect her to be strict and no nonsense.
If I was the doctor, I would do the same to my hot female patient: coax, cajole once, then lay down the law!
In neither case would spanking come into the picture.
I guess, it's because I have never experienced a spanking at or by the doctor.
Do the folks who have experienced a spanking at/by the doctor think I have missed out on something erotic and pleasurable?
