Is there a fomula of raising teenagers other than talking to them honestly as young adults ?

I am in my early 30's and leaving with one aged 19yrs . Times have changed since i was once a teenager but the tricks are still the same.

We talk about life and sex,but the amazing this is they are more afraid of getting pregnant than catching hive,or stds. Through our talk times,i realise that they act and react to life depending on the circumstances around them,thereby arousing positive or negative attributes.

So,how can we as the youth influence the young adults in our lifes?
