Exactly.

The paradigm this sets up is that the parent/guardian has the opporunity to make their own response to a kid asking about it.

I'll tell you when you're older

Well timmy, some girls like boys, some boys like girls... etc

Its a delicate topic, theres no one size fits all solution for all different kids, and giving the parent/guardian the responsibility and ability to direct how that goes is far superior to just a censor deciding no children nor parents are capable of handling this.
