Just out of curiosity: What do you say when you are referring to the female genitals in your family, when you are talking to your kids? Do you have like a nickname for it? Eg. referring penis as kuku bird.

My parents, especially my mother, are very typical conservative Singaporeans so they almost don't even mention it at all cost. For me, I use the term "private parts" so it's easier for me to explain why she's supposed to keep it private and only for herself to see.
