Well you had to go and invoke me didn cha, Kriston
So now you have to hear my related story.
When dd was 2.5 or so she was in a daycare that had a large unisex bathroom for all the kids her age.
She pointed at one of the boys and said "boys have a p---s but girls have to sit down because their urethra comes out from the vulva."
We had mentioned this stuff only once months before when she asked a large number of body part names and we never discussed the physical relationships between parts and we had never had any discussion of boy parts or differences. Luckily the daycare teacher thought it was funny and very much enjoyed my discomfiture as she told me the story....
