From an early age I was familiar with girls vaginas from playing doctors and nurses, but had never seen an adult woman naked except in high art and pornographic pictures, which in those days always had their pubes airbrushed out. I therefore thought that as girls grew older, their vaginas must slowly migrate round towards their backsides.
