I agree with @robin62t you should have had a parent/guardian with you, at least in the room. Could you give a little more info about your Dr. Visit? Don't
worry no weird questions. What was the physical for, was it for health reasons or for signing up for sports? I can think of very few reasons a Dr. would need to do an exam with the patient in the nude. From what you described, it sounds like it was for a sports exam. I see no reason for a nude
exam for this, it could be done wearing underwear. I suggest you tell your Mom/Dad ( if you haven't yet) what happened in the Dr.'s office, so they can take the proper steps to make sure this never happens again.
Yes, from what you've said this seems inappropriate. Didn't you have a parent with you? Surely there should have been?
