How old and how developed were you the first time you had to take off your bra for the doctor? Male of female doctor? Was the doctor a gyno or a pediatrician/family practice doctor? Did the doctor examine your breasts or just listen to your chest?
Mod note: This post is searching more for feelings about something that happened long ago, and particularly, how that informs your kink today, not a graphic description of something that happened as a child.
