If i break my hymen while masterbating does it mean iam not a virgin anymore? also if your hymen breaks will it heal?

Still a virgin: It may or may not heal partly, but 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.
