Can a gynecologist tell if you had sex?

Signs of sexual life. If your hymen is gone or torn then the gynecologist may assume. But, this can also happen with inserting tampons for your menstrual period. Your gynecologist will only care that you are sexually active to the point of teaching you how to prevent pregnancy and sexually transmitted diseases. Doctors are like priests. We have a solemn commitment to confidentiality and not being judgmental.
