There is no depth to the hymen, which covers the vaginal opening.
Located at the opening of the vagina, the hymen is a mucous membrane tissue that can be easily torn and serves as a protection for women. As a result, women who have not had sex are relatively less prone to gynecological diseases. The hymen is rich in microvessels and nerve endings, and women are prone to bleeding and pain when they have sex for the first time. Since the hymen is located right at the vaginal opening, everyday strenuous exercise can also cause it to rupture.
Individual hymens are tough and require surgical incision, but are extremely rare. If you bleed excessively during your first sexual intercourse, you should be wary of excessive hymen tearing or rupture of blood vessels in the vagina, and should seek medical attention promptly.
