Dinkydoo i’m exactly the same as you! I’m very shy and don’t like anyone seeing my bits lol But you have to remember that these doctors have seen thousands of breasts on thousands of bodies. They’re more worried about getting the measurements right etc so they won;t be getting any kicks of it!
All your worries are inside your own head….just keep thinking that he’s probably seen so many other boobs that day so you shouldn’t feel embarrassed!
