If you haven't checked your child's sexual knowledge lately, you may be in for a surprise. Our kids tend to be overstimulated and underinformed. For instance, current cultural trends have led teenagers to believe such fallacies that only sexual intercourse is really sex. Teens need to know that purity of heart and mind is as important as technical virginity. Meanwhile, we as parents often assume that our children aren't even interested in the opposite sex when they are already experimenting.
Kids have anonymous access to internet offerings.
Parents used to check between the mattresses for stashed girlie magazines. Teen magazines aren't the innocent fashion rags they once were. Be aware that sex is more risque and less mainstream in the media than ever before. Aids is not the only nasty virus out there, and penicillin can't cure everything. See Herpes for accurate, if frightening, information.
