names for 'private parts'

[twinterror]

my dd has started showing an interest in her own privates, I have never given these a specific name (apols if I am coming across as a prude) - what do you call them in your house? I don't want her shouting out 'I've got a vagina' at nursery/shops etc (she already talks a lot about breasts very loudly in the most inappropriate circs).

Winny - DD knows penis and vulva but DH is a shy in that regard hence their other names.

winky for Ds penis, although i was baffled when he grabbed his testicles in the bath and asked what this bit was called. I managed to say testicles but DH was horrified, what should i have said i wonder! (DS is 2.5yrs by the way)
