I have a son. Willy seemed most obvious choice for his privates. Feels ok to use in front of friends, family, nursery and playgroup. It is clear what is meant. But now he wants a name for the female alternative, the vagina.
There is no clear female equivalent. Fuffi, fairy, crimons seems unclear. Vagina too clinical and I've been told fanny could cause offense.
What do you use?
