This is true, however, not realistic in some parts of the world. For instance, in the United States, Republicans have waged a war on bodily autonomy, which includes the Roe v. Wade ruling and states creating departments to hunt down citizens who go out of state to have abortions. There are also countries where sex education is not prohibited. So, take these things into consideration while thinking about potential solutions. That being said, you are right, and you can do something about it by voting, if you are able to, wherever you live.
