I also prefer the doc to be female. I found over time that the male doctors are rude and insensitive to my concerns and ailments. For example, I had a pain in my arm anytime I lifted it a certain way. the pain was enough for me to be concerned something might be wrong. The male doc heard my complaint and said, "well don't lift your arm that way. Is there anything else?" then left the exam room on to the next patient.
My female doctors over the last few years have offered follow ups and suggestions for what ever I had discussed with them. They also seem to ask pointed questions, instead of "Is there anything else?"
I am not concerned, turned on, or excited to see a female doctor, even when I need to get naked. I also have no problem with a male doctor seeing me naked. I am what I am and if they don't like it, then too bad for them. I am comfortable being naked under the proper conditions, doc exam, locker room, nude beach, but I am shy when someone sees me naked without the proper conditions being met.
I had seen a male derm doc. He could have been shopping for drapes or playing golf in his head. He certainly was not into my derm exam and any spot I pointed out he responded, "I have seen worse, no need to worry about that yet." Yet? Really? I wish I could have had a female derm doc. Know any that are willing to take on a new patient?
