While I can see where she's coming from, I have to strongly disagree with her view point.
Feeling that virginity is important in itself - and that sex is a dirty, primal thing is definitely not what she was being taught, but it is what a lot of girls hear. Why? We get told repeatedly that virginity is preferred until marriage - but then nobody talks to us about transitioning into a marriage (and sexual) relationship.
As far as being controlled by any religion, no way. Again, her religion taught her half of the principle: waiting til marriage. Then everybody else left the sex talk up to everyone else, so of course nobody did it.
We waited until marriage, and I wouldn't have it any other way. However, we also talked about expectations, desires, and such before we got married so that our honeymoon was none-of-your-business fun. That conversation wasn't a one time thing, as my own family had neglected such talks with me, leaving me to figure things out via anatomy classes.
Basically, education is important in
any subject - but you have to have it beforehand for it to be useful, otherwise you get to end up in therapy due to unintended physical or emotional scars.
As far as finding that education, there's a lot of places to go. If parents are uncomfortable talking about it, perhaps there's a trusted adult to turn to or there's always books. There are lots of tastefully written books that can help guide conversations - we used one written by a pastor from a different denomination and, with the exception of one section, I highly recommend it.
