Just been looking at book about the human body with my 8 year old boy and got to an 'interesting' part
"Dad, what is a penis?"
"Erm, the appendage between your legs" (I do try to use proper words with him so was surprised he asked)
"Oh. I thought that was called a peanut"
Reminded me that until the age of 14 I thought that a common term for oral sex was a 'hedgehog'. It seemed to visually make sense as well. Fortunately I found out the truth before I first asked for one.
Now contemplating what must have been going through his head when we last shared a bag of nuts.
Went on with book that then described how babies are made.
"That sounds messy". OCD from mother is clearly genetic.
