I'm 16 and since i can remember my left nipple has been inverted. Nothing makes it stick out even using different methods and sometimes it's so inverted it looks like a hole because it's drawn in so much. It's not been an issue for me yet as i'm not sexually active but i do get anxious and insecure about it as i don't want anyone to know and i just want it to be normal. I've briefly mentioned it to my mum but she just brushed it off saying it's fine and i'm too scared to say something again and go to the doctors. I'm worried that one day it will show if i'm wearing a top with no bra and you can only see one nipple.
I really am not sure what to do and it does make me anxious when i think about it, should it be something to worry about and how normal actually is it to have it this young?
