In the 1740s a little-known English excise officer and master of a charity school published a frank memoir of his life. John Cannon wrote extensively of his partnerships and his marriage, and also of his sexual exploits. Beginning at the age of twelve, he was taught to masturbate by a school friend and he continued with this until his early twenties. From this time, he had regular sexual contact with a variety of women, including one relationship of ten years. Yet he rarely had sexual intercourse. Instead, his very active sexual life was filled with kissing and erotic fondling: for Cannon, penetrative sex was saved almost exclusively for marriage.
