The problem with virginity tests centering on an intact hymen is that the membrane may break due to other causes too. Masturbation, intensive exercise or physical activities like horse-riding can cause the hymen to rupture. Thus a girl who has a broken hymen may be labeled sexually experienced when in fact she may never have had been touched by a man before.
Yet another problem associated with this kind of virginity test lies at the very heart of the concept of sex. What exactly constitutes sexual intercourse? Is a girl who has not had a vaginal intercourse but engaged in other forms of sexual behavior like oral intercourse or heavy sexual fondling still a virgin? There is great debate among educationists, the medical, legal and religious community on what exactly determines a sexual act since it varies from one culture and historical period to another
