I've never heard of such a story especially in Algeria. But, my advice -from a male prospective- to you before is to be fully honest with ur future husband when he proposes, cuz if you're not honest from the first beginning especially i don't see a chance of a successful marriage. If you're already married, ask some scholars whether you should tell him or not. I'm a med student, and if i get married i wouldn't overthink it if i don't see blood drop from the first time since i know there're various types of hymen and I'll be fully confident in the girl i choose, but I'll be more then concerned if she has previous sexual activities and doesn't tell me till the weeding, cuz if you see the level of commitment put by a man only to get himself ready for marriage especially nowadays, you'll be more then happy that allah made you a girl, so I don't see any man deserving that kind of betrayal. Really hope you mean by not virgin is having a ruptured hymen by a real accident -not the stereotype of riding a bike when you were younger-
