6. Take a strong stand against your daughter dating a boy significantly older than she is. And don't allow your son to develop an intense relationship with a girl much younger than he is.

Older guys can seem glamorous to a young girl - sometimes they even have money and a car to boot. But the risk of matters getting out of hand increases when the guy is much older than the girl. Try setting a limit of no more than a two- (or at most three-) year age difference. The power differences between younger girls and older boys or men can lead girls into risky situations, including unwanted sex and sex with no protection.
