What are your thoughts on parents who don't give their kids the sex talk at any point in their lives?

They're probably in the majority.

It is their business.

I would call them grandparents soon.

It depends on their parents views on it.

I believe it’s a personal choice, most children learn it in school nowadays unless they’re home schooled or if their parents don’t allow them to attend the sex Ed. The majority will learn it on their own at some point in life, I don’t think it makes them bad parents.. it’s old style, and that’s completely okay

Frankly, most adults probably aren't that well educated about the topic of human sexuality to begin with. I mean, just look at how many people think that biological sex and gender are the same thing. They're not.
