DS2 (4) wanted me to wee standing up with him today.
I have talked to him about this before but obviously it hasn't sunk in.
I said I haven't got a penis, I've got a hole I wee out of, in fact, 2 holes, one for the baby to come out of and one for wee (or should that be three if we're getting onto poo but I think he knows about that!!)
So then he wanted to have a look, so I said not right now, I'm on the loo, another time.
In theory I'm fine with it, they see me naked a lot (out of the shower etc.).
But considering I only discovered my own "bits" at age 16 when I started my period, I am feeling squeamish. 
Would you/have you?
