Ugh, I sooo know how you feel. I first went to a gyn at age 10 - if that wasn't scary
Those doctors have seen everything, so I doubt anything about you will shock them. Try to stay calm and remember that your mom is always there should you need someone to come to the appointment with you. Millions of ladies do this, so you are far from alone. You came to the right place for advice - there are a lot of great women here who can give you support and help if you need it
Hope this helps...it'll be alright, just remember that your doctor isn't being a perv, they're just doing what they do countless times each day, it's nothing new to them.
