Please, do not restore thorn hymens or, at least, consider well what are you talking about.
First of all it is an hoax, a lie, a ruse. We are not talking of resetting time and memories, we are talking of, simply, construct an artificial membrane with no purpose other than be a physical virgin while not being really someone who never had sex before, so basically we are talking about tricking other people (because you know that it is not true that you never had sex in first person, so the only one who will believe it is your lover).
In case you do not tell it to your partner, your partner is getting tricked. In case you do tell him, he will know it will only be a physical presence with no meaning, so in both case there is no real virginity or meaning.
What is worse is that it is not always nice to have to lacerate it. It can cause pain and bleeding, and i will personally not be glad to make my lover bleed or suffer if avoidable. Imagine to hear "I lost it but i placed it back so you can make me bleed and suffer again!". Borderline psycopath? Supreme fundamentalist? Magic pratictioner? I will be a little scared of a similar person (which by no means will be virgin anyway so the main goal is unreachable).
Bottom line: restored hymen doesn't mean that someone gets back her first time. First time is gone (luckily).
It also does not mean anything. There are virgins without hymen and there are some who are not virgins and still have it.
With knowledge we reached a point where we debunked a lot of facts and we know now that it doesn't pertains exclusively sex, nor it grants magical powers to rituals of dark magic or religious virtues.
We know that it's just something in the way of a nice experience which will make it worse.
