When i was younger, i used to believe that many women, when they grew up, grew penises. I Also believed that some girls i knew secretly had penises. I used to think all these 'dirty' people combated their 'problem' by using 'willy-remover'(and that is what i thought it was actually called aswell), a white paste in a blue paper sachet that they applied on the 'problem area' with a spatula.
