Sorry, but shouldn't that be chastity? Calling it "purity" makes it sound like Reinheitsgebot, German beer purity
No, there's nothing wrong with virginity, just as there's nothing wrong with sex outside of marriage: just don't be stupid about it! That is, be responsible--BE CAREFUL! Know what you're doing, and be respectful: don't make someone feel like a horrible person because they've had sex and you haven't: "slut-shaming" is a really crappy thing to do.
On that note, why is it OK for men to whore around, but if a woman does it, that makes her a tramp--WTF!
Just a thought,
