Thank you for the opportunity to help you with your question!
My response to this paragraph would be:
It feels too biased to read that teaching about masturbation in schools should not be done because of the age it could begin. Where is the proof of this? I would say that viewing both sides of the issue is important, and why is no one really arguing that it could help. I was able to find some support for teaching sex ed in school. For example, the Washington Times (2015) even reported that Las Vegas schools are considering teaching about homosexuality and masturbation to kindergartners. That seems very young to me, but there is definitely evidence to support that it helps children as they grow.
Please let me know if you need any clarification. I'm always happy to answer your questions.
