it doesn't heal there are surgical procedures that can be done to replace it
There is no such thing as an unvirgin hymen the hymen is broken during intercourse.
Here is an article on the hymen: http://en.wikipedia.org/wiki/Hymen
Males do not have a hymen. Theoretically, you can say that the male's foreskin is their hymen equivalent, as it serves the same purpose for the penis as a hymen does for the vagina.
There are no exercises to break the hymen. The hymen cannot be broken but can be torn if penetration is rough or forced, simply exercising is not going to tear the hymen.
The hymen does not disappear , it can only break.
Yes it is possible because you can either miss the hymen or you can hit the hymen. And when you hit the hymen that's when all the pain comes in.
The hymen is tissue that surrounds the opening to the vagina. The hymen is the same in a virgin as it is in someone who has had sex, although sometimes sex can stretch or tear the hymen.
You know the hymen is in tact or not (the hymen does not break, it can tear) by looking. A woman can just look at her vulva in a mirror and see whether the hymen is in tact or not.
The hymen cannot be broken, the hymen can only be stretched or torn. You know if the hymen has been torn because you can see it when you look at your vulva.
You can't break your hymen - your hymen can be stretched or torn, but there's no reason to purposefully tear your hymen at all. You can stretch or tear your hymen via vaginal penetration, to tear it would require force or rough penetration: again, there's no need to tear the hymen.
