Virginity has nothing to do with an intact hymen. You're a virgin if you have never had sex. You're not a virgin if you have had sex with another person. Depending on how you want to define virginity... whether it be only penetrative sex vaginally or anally or blow jobs with the opposite sex or only vaginal sex.Wouldn't Laura be forever a "virgin" because of her healing factor repairing her Hymen after or even during sex?
Edit:
Thinking about this more and looking her up on the wiki's of the internet she apparently regrew a lost arm at one point so her healing is not just healing but regeneration that should mean that her Hymen would constantly regenerate during sex meaning it would also constantly be being torn, sex for her would suck as it would never move past that very first penetration.
At least until me fucks Zero that is, because Zero can negate that power though contact if zero fucks her and then spend the night next to her her hymen would have enough time to "heal" in the normal way stopping future regeneration, so from a certain point of view she could only ever truly lose her "virginity" to Zero.
Edit 2:
This would actually also fit into her comment about getting the rougher customers, the ones that like to "break-in" a virgin, but this is a porn game based upon a cartoon that's based upon a comic so the real answer is it works however the author want it to.
If you went to school and took biology or basic sex ed class at all they should of taught you that a hymen has nothing to do with virginity, because a girl can break her hymen through any strenuous activity... through masturbation or even just exercising, or horse back riding ect... just because a girl's hymen is broken doesn't mean shes ever had sex.
In the Middle East and Asia its not uncommon to hear that women get surgeries to basically rebuild their hymen when trying get married to either trick men into believing they are a virgin when they are not or to simply feed into the misconception that you have to have a intact hymen to be a virgin.
