CMV: If you were a child, you would be mortified at the thought of your parents talking about sex

I'm a uni student and I was talking with some of my friends about this. The consensus seems to be that any mention of sex from your parents is embarrassing, even if you yourself are sexually active. I would want my parents to never mention sex under any circumstances. If I was a kid I would never want to even **think** about the fact that my parents have sex. I think this is enough to CMV, but if it isn't, consider that the other possibility is that your parents don't have sex at all.
