Welcome to ehealthforum,
The hymen is made of connective tissue membrane and is located in the entrance of the vagina. It usually has a round or elongated hole in the middle through which the menstrual blood flows. It might be perforated by sexual intercourse, but there are various other non-sexual activities might cause the hymen to rupture as well.
These include exercises that might rupture the hymen like: riding a bicycle, horseback riding, and gymnastics, etc. Trauma or injury or even inserting fingers or instruments in the vagina during a medical examination or masturbation might also easily rupture the hymen. Tampon insertion could sometimes be a cause for hymen rupture if the walls of the vagina are too tight. The ruptured status of hymen can be confirmed by a gynecologist after a thorough examination.
