Welcome to the world of hymen reconstruction and fake blood capsule, a booming industry that preys on sexual inhibition, medical ignorance, and cultural anxiety.
According to a common urban legend, if you don't have sex for seven years, your hymen will regenerate. Needless to say, this is not correct – it is not the size of a fingernail. It's gone once it's gone.
Traditionally, an unbroken hymen has been simulated with another piece of material pushed up there in its place. Sites like Bevirgin provide kits that allow women to impersonate their virginity every time.
