My place ask my preference male or female. If you want a female, ask for one. It is important that you feel comfortable being able to open up to the T. Therefore, feel free to make this kind of a request if the topic is a female hormonal topic. I know I would not have wanted my pap smear done by a male doctor. (I forget to ask before the appointment. But, she wasn 't a man. Thank God.)
Good Luck.
