When it comes to when the time is right for people to have sex though, I don't think that can be determined by using a universal standard. That's because we humans are as unique and varied as the snow flakes falling from the sky. No two of us are exactly alike (including identical twins).
So when someone tells me they're ready for sex, all I'd suggest to them is that they do it safely. And of course, I'd tell them to have a good time.
However, ever since those incidents I've vowed that the next time I engage in frivolous behavior will be in a relationship with a significant other.
Each person is different in regards to preparation and readiness for this nocturnal activity. I don't think we should actively teach children about intercourse, but when the time comes we shouldn't hide it from them either. The human body is a wonderful thing and the things we can do with it (even in the bedroom) should never been something taboo.
I agree with everyone about abstinence programs in high school and even middle schools. Sex ed should teach our youth about sex, not abstinence. Abstinence is not sex, and our educators are pretty much presenting it as sex.
Our health teachers always told us that the only way to be completely safe is abstinence. I don't remember what they said, but it implied that abstinence was intercourse itself which made absolutely no sense to any of us.
Two cents. I'm out.
