Patrick Welsh's article on teen sexuality {Outlook, Nov. 29} is a tragic, real-life parallel to the "Emperor's New Clothes." Our young people are walking around stark naked, and the thinking represented by Mr. Welsh's piece offers them no coverage. Mr. Welsh is blind indeed if he thinks for a minute that these kids know what they are doing or that the new code of ethics that is emerging from the behavior he describes will enhance our society.

He and others should read Josh McDowell and Dick Day's study on the teen sexuality crisis, "Why Wait?" Mr. McDowell and Mr. Day have compiled research and resources from a survey of thousands of young people, who relate the pressures they encounter daily. What they report of our young people's struggles is deeply touching, and their research and conclusions are most illuminating. Mr. McDowell and Mr. Day offer concrete solutions for adults who are willing to help teens to grow up.

The activities Mr. Welsh is apparently unwilling to confront result in the death of unwanted children;ever-increasing Aid to Families with Dependent Children, Medicaid and food stamp payments; and the alarming increase of deadly public epidemics. Adults are unwilling to live the values we wistfully dangle in front of kids, hoping they will not get into too much trouble before they are on their own and out of our hair.

So, just like the citizens of that fairy-tale empire, Mr. Welsh won't tell our kids the truth: premarital sex has a huge price tag. For mental, physical and emotional health, kids must save sex for marriage. BARBARA SMITH Annapolis

I am certain many readers will rush to condemn Patrick Welsh for telling us "how it is" with respect to sex and today's teen-ager.

Based on my own observations as a teacher at another large metropolitan high school, I believe Mr. Welsh's comments not only accurately depict the moral philosophy and sexual attitudes of teen-agers but also provide all citizens with a much-needed insight into the value system of current American youth.

Whether or not we agree with the ethics of these teen-agers, it is important that we not bury our heads in the sand pretending that they value the same behaviors that characterized earlier generations. This is not to say that we should lessen our efforts to teach them moral values, but rather that we must recognize the reality in the schools. Mr. Welsh has done a great service in painting that reality. ED LINZ Springfield
