In the digital age, life has accelerated. Wee kiddies and teens are now exposed to the most graphic pornography at the stroke of some keys or some taps on a smart-screen. Better to arm them with age-appropriate knowledge of what they're going to see and talk about with their peers then to cast them into the sexual wilderness of an adult world without any preparation. As long as the sexual education informs, but does not promote sexual behaviour and as long as those teaching are well prepared and without an agenda, I think the earlier loss of innocence can be justified by the prospect of better protection for the children and teens.
Sexual education should be carefully crafted to be age-appropriate for the students receiving it. Elementary children do not have to know about how to put on a condom or how to safely take birth control pills. But they should be able to figure out when they are the target of others' sexual advances and how to get help if such a situation ever emerges. Very young children (Grades 4-6) should learn about their bodies and what sexual reproduction is and why it is necessary and natural. This should be done in conjunction with teaching them about plant and animal sexual reproduction. They should also learn about the consequences of sexual behaviour and the dangers of premature sexual activity. Finally young children should be made aware that some people choose or feel compelled to adopt alternative lifestyles without going into too much detail about the "plumbing" and social implications of those lifestyles.
By middle school and high school the curriculum should expand to include specific eduction about abstinence, contraception, prevention of sexually transmitted diseases, sexual hygiene, abortion, parenthood, fostering and adoption. They should also be counselled in the emotional and psychological implications of entering into the adult sexual world when they are ready. They should be educated about the personal and social pressures they will experience or are experiencing in order to become sexually active and then taught appropriate strategies and coping mechanisms to avoid unwanted sexual activity until they judge themselves ready for it. They should be encouraged to talk to their parents or wider family before making any monumental decisions about their sexual lives. They should be fully informed about their rights, responsibilities and consequences of an active sex life and be fully informed of all medical options, rights and responsibilities available to them. They should study non-binary sexual situations/lifestyles in order to demystify (and perhaps make less attractive) these other sexual lifestyle alternatives (due to attraction to the forbidden and teen rebellion) but should also be fully informed of the legal, social, professional and biological challenges which go along with choosing or feeling compelled to adopt any of these lifestyles. They should also be educated in baby care, basics of parenthood, medical responsibility for infants, vaccinations, first aid and CPR, etc.
