You remove your clothes, put on a gown, get onto the gurney and they take you into the OR after consultation with your surgeon, OR nurse or anesthesiologist. Once in the OR, they take off your gown usually after you are asleep. As soon as that happens, you are draped for the procedure. You are NOT naked during the procedure. Only the surgical area is exposed, absolutely everything else is covered, and that usually happens quickly, using large drapes to cover major areas and successively smaller ones, until only the area they are working on is exposed. For example, for a D&C, the area exposed showing the vagina is about the size of a 4x6 index card. The vagina is completely out of context of being connected to a person. It isn't a big enough area for anyone to get excited over.
Besides, we've seen it all before, and it's only an anus, scrotum, penis or vagina or any body part covered by your underwear or bathing suit. I can tell you from first hand experience, once you've literally had your hand in a few doing real hospital exams, one is just like another, and while those parts are connected to a person, they are in fact, just another piece of gland, organ meat or muscle. It isn't a big deal. It doesn't become a big deal unless you are emotionally involved. A real breast, hernia or prostate examination is very different from doing the same activity while playing with your spouse or S.O. Your physician doesn't think anything more about examining your prostate than you feel about ckecking out a good piece of fruit in the food market. It's his or her job, and that's all. When I go to my gynecologist, I know he DOESN'T think to himself, "Oh wow! I'm going to see Susan laid out naked and vulnerable and that turns me on," because I am just one of many patients he sees in the same position. But, when my husband and I go to bed at night, I know that's EXACTLY what he thinks, and that turns both of us on, and I'M GLAD. A real examination by a physician is different from a play exam because of the professionalism, the lack of emotional involvement and and your expectations in a professional relationship.
