GYN Visits.

Okay, so I'm 17, I've been sexually active since I was 15. I am so terrified of having a PAP Smear done. I've been to the GYN and I've been STD tested and have had the doctor feel around in there but the thought of that metal thing terrifies me to the point of making me feel physically sick. I don't know what to do.. Do women really have to go every year..?
