What I don't really understand about viewpoints like that is WHY does losing your virginity have so much more importance than any of the rest of the times you have sex? I assume that it's still sinning just as much in the eyes of God as the first time was, but people don't treat it like that -- it's like turning in the v-card is a major sin and after that it doesn't really matter what you do. IMO we attach FAR too much importance on losing your virginity in this society and not enough on the sex that comes after that, which leads to situations like these where kids think, "Hey, well, I didn't want to lose it but since I have, I'll just keep having sex!" (which, in conjunction with the "you should wait until marriage and we aren't even going to imagine any other possibilities" brand of sex ed, leads to the fact that a lot of these kids start having sex and DON'T use protection -- fantastic!
)
So yeah. Effective sex ed programs and even effective abstinence-only programs need to be able to work with the kids who have already HAD sex, to get them to see why abstinence after losing your virginity is still possible and important. Too many of them write these kids off as failures, and so these kids end up feeling caught in limbo where they still think of sex as sin but they're not accepted in the virgin camp anymore.
