Firstly, the notion that the parent will be able to accurately determine when a child needs to receive information on contraceptive options and the importance of engaging in safe sex is fundamentally flawed.
Teenagers are notoriously disengaged from their parents and are unwilling to share details about their lives— particularly the details surrounding love and relationships. Making the parents the gatekeepers of that information, who often see their teenagers as much younger and more innocent forms of themselves than they actually are, could leave teenagers in the dark about safe sex for too long.
The second false assumption is that just because one teenager didn’t receive a sex education lesson from their parents or their teachers, they won’t be exposed to the information. Teenagers talk. By taking the teachers out of the equation, the only thing that will happen is the teenagers will look to their friends for information.
When this happens, there is no way of controlling the information they receive. If one student knows more than the others, they will share. This is how misinformation spreads. Teenagers may turn to pornography to glean a better understanding of sexual relationships, which will likely be far more damaging than a simple sex education class.
With a comprehensive sex education program in schools, teachers and parents can ensure that every child receives accurate information.
