I guess that I have to admit to being a Perve for almost as long as I can remember...
For a reason that I cannot recall I had an incredibly vivid fantasy when under anaesthetic gas at the dentist. There was the sound of bells and a woman tied to water-wheel going around and under water.
Didn't tell my parents but tried to ask at school if any other boys dicks kept "sticking up"! They thought I was hilarious as they didn't know what I meant.I was 7.
