Is it normal to be nervous to have a pap smear done for the first time? I'm a virgin and someone told me that during the exam it can break your hymen?

No need to get a pap. If u r 17 and a virgin there is no reason for u to get a pap done. U have wait until u r 21. Also if u r a virgin, u just need to let the dr know so they can use a smaller speculum. As for the nervousness, all women r nervous about it. It might be necessary but it is by no means natural.
After 21 years of ag. The first Pap smear is recommended after 21 years of age, so seek gynecologist's advice. Why do you need to have one done now???
