(Mine was in the OR during my surgery, at our request. She was an RN and was allowed in as a professional courtesy. She was not allowed to participate, though, due to hospital rules.)
I hadn't given it much thought as to whether I would prefer to have castration and penectomy performed by a female or a male doctor. I have always been a firm believer that any medical procedures should, however, be performed by a qualified surgeon under proper surgical conditions.
Until recently, my doctors were always been men as that was the standard. However, I have had a female primary care doctor for the past 1½ years. She has not yet given me a physical or examined my genitals. I know that she is a doctor and I do not consider it to be an erotic experience just somewhat of a modesty concern.
Back to the original question of whether it is better to have a castration and/or penectomy performed by a female or a male doctor. If given the choice, I guess that I would prefer a female doctor. I feel that she would be more sympathetic and understanding. Most men tend to view those things as something great and as being the pride of manhood.
I desire nullification, and want it done by a female. I have never been comforatble around males and could never even discuss this desire with a male. I don't think I would care if a female cutter or doctor did it as long as she knew what she was doing and it was done safely as when it is done I want to enjoy by nullified status!
