Does clitoral stimulation or clitoral orgasm cause the rupture of the hyemen ? because i saw a small quantity of blood in my underwear after masturbat

It doesn't matter: No. Yes. 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 or are not broken. No worries.
