I should have very much liked to find out how it was that when two mouths came in contact people got voluptuous feelings: often, looking at the lips of a young man or a young woman, I would feel amazed, just as when I used to gaze at the live rail in the Métro or at a forbidden book – what could it be? The information Madeleine proffered was always rather odd: she explained to me that physical pleasure depends on one’s personal tastes: her friend Nini couldn’t do anything unless her partner kissed or tickled the soles of her feet.
