Religious and political issues are less contentious when school campaigns are devised by local medical personnel. No sexually active person who engages in unsafe sex is ever immune. Ignorance can be deadly. There are many resource materials available to schools and communities on age-related curricula. Children can be taught that another person s bodily fluids should be avoided, e.g. not ingested.
Sex can come later.
Sex is not bad or unhealthy in itself. Only unprotected or high risk sex is highly dangerous. Condoms can fail as the result of poor quality or improper use. But the use of prophylatic barriers are safer than not using them. Different sex practices carry different risks.
