Please understand that in this era, sexual intercourse is not the only cause for rupture of the
hymen. Now women are moving out of the house, participating in so many events which can rupture the hymen.
The common causes, apart from the intercourse, for rupture of the hymen are cycling, climbing the treats, athletics, rigorous sports, any reason when she has to sit astride or stretch the legs too fat apart.
No my dear, intact hymen has not remained a test or sign of virginity now.
So why are you so much concerned about intact hymen.
Still if you are very much keen on it, a plastic surgeon may help you in doing this.
I hope you are properly counselled by relevant information.
