How does the doctor know if you are a virgin?

A health care provider knows you are a virgin if you tell him. The words "virginity" and "virgin" have no medical definitions, explains WebMD. Colloquially, many people use them to refer to a person who has not yet had sex.

Some people believe that when a woman's hymen is broken, she is no longer a virgin. However, the hymen, stretchy skin covering the opening of the vagina, can break from many physical activities that are not remotely sexual in nature, according to WebMD. In addition, some people believe virginity ends when someone engages in oral or anal sex, and these activities do not break the hymen.
