We use doodle and hubs taught my son bajingo for vagina ( all scrubs fans will know that one).
We are NOT embarrassed of our genitals, I don't remember ever feeling like it was a taboo subject just because we didn't use the correct terminology, I never found a problem with not speaking the correct terms when growing up ( I knew what was what and where everything went and what it all did). You use what you and your family are comfortable with.
