There is no such thing as an unvirgin hymen the hymen is broken during intercourse.
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.
It is possible that he will find out, since virgins have a membrane called a hymen which is broken the first time that they have sex. However, there are other activities than sex which can break a hymen, for example, vigorous horseback riding. So the state of the hymen is not absolutely conclusive. Chances are, if your groom is at all courteous, he won't even enquire about it.
The hymen cannot break, it can be torn as a result of rough or forced penetration. You can identify a torn hymen by looking at the hymen, if you know your body well you will be able to see the tear.
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 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.
The hymen is a thin membrane that partially covers the vaginal opening. The shape varies but a typical hymen is crescent or half-moon shaped and is below (or to the rear) of the vaginal opening. See the picture and article in the related link below.
No, the hymen isn't in the abdomen.
