This seems like a dumb idea, but if a woman wants to do it, it's a free country. Even dumber is the link in the OP that is critical of the idea, even though the writer claims to be in favor of women'a rights. She blames the idea on men, which is par for women of her sort to do. I am referring to American men; I say nothing about men in other cultures or nations.
I would venture to say that most women are not virgins on their wedding nights, and their husbands don't care very much one way or the other. I say that because most men would want to have sex before marriage and, if the woman said something such as: I'm saving myself for marriage," they would lose all interest in marriage to her. Most brides are not 16 ot 17 or 18 years old, but are in their twenties or older, and should have developed a strong interest in sex by that time. As far as I am concerned, if I were a younger man and was courting a 22 year old woman and she insisted in remaining a virgin until our wedding night, I would let her remain one forever.
ETA: What is vajazzled? I read about it, and the writer of the link complains about it, but never says what it is.
ETA: Okay, I googled it and, apparently, it is just fastening patterns of beads around the pussy. Not something I would admire, but doesn't sound any worse than tatooing and not as bad as nipple or clit piercing.
