If i ask my gynecologist not to mention the hymen breakage (even if they ask specifically) must they abide even if i may be a minor?

Yes: Patient confidentiality protects you from the sharing of this information with others even if you are a minor.

Yes ...but...: Most docs will keep such issues confidential if you ask, but it will be recorded in the medical record for accuracy. Federal and state laws permit the parent of a minor to obtain copies of office notes if they decide to go trough the procedures needed to get them. Since a hymen may be broken in non sexual activities at any point, or may not be present from birth, the issue should not be overrated.
