across the lower part of vagina. The upper part of your
vagina is open to allow the passing of urine and blood
during your period. The hymen is on the outside of the
vagina near (1-2 cm) from the genital lips.
The hymen is a thin and prone to tearing. These layers have blood vessels and nerves. Therefore, a tear in the hymen is often accompanied by bleeding and pain.

These women may require a gynecologist to perform a medical procedure called a hymenotomy to allow menstrual products to escape. Still other women have unusually thick hymens that may require a hymenotomy to prevent pain for the woman during sex. In a woman or girl past puberty, the general structure of the hymen can be compared to a hair scrunchie in that it is elastic and stretches open easily Some other common forms of hymen are:
Annular – in which the hymen forms a ring around the vaginal opening.
Septate – in which the hymen has one or more bands extending across the opening.
Cribriform – in which the hymen stretches completely across the vaginal opening, but is perforated with several holes..
