I'm a virgin nd my hymen is not intact!m worried, what can b a reason to it?only physical exercises can cause a tear?or by birth few hymens not intact?

It doesn't matter: It doesn't matter. It doesn't matter. So, ignore the hymen. Usually, only in cases of alleged sexual assault upon girls and women do we physicians engage in the careful examination of hymens, collecting evidence of physical damage to be used later in courts of law. In normal everyday life, people should not be "checking hymens" nor thinking about whether they are broken or not broken.
