> Because it's creepy and weird for adults, who are supposed to be teaching math and so on, to have conversations with young children about sex.

If kids don't learn about it from the good adults in their life, they're going to learn about it from the dangerous adults in their life. CSA thrives on the culture of silence imposed by those who think any discussion even obliquely related to sexual relations (and you're the one saying having two moms is "about sex"!) is inherently "creepy and weird".

Kids have a need to learn words to describe things which might be happening to them, and a right to see their self-image, family structure, and any proto-romantic/sexual feelings acknowledged.
