Well, I don't know how common is hymenoplasty in Pakistan but I do know that sheets are checked here. Someone I know had her husband point a gun at her asked her regarding the non-existant proof he was looking for. The girl hadn't done the deed before but for some reason didn't produce enough 'proof'. That happened about 12 years ago and she is still leading a crappy life. (BTW, the sheets were checked by MIL in this case in the morning).
Ok, hymenoplasty is the way out but does it make everything okay? I don't think it does. How can one go on living like this without feeling guilty?
How awful, that is so sickening that people do this.
I have not actually ever heard of this being done from any members of my own family who are married, or from anyone i know in pakistan, so may be it is restricted to certain groups, rather than national thing.
I think it is common in Egypt tho.
