Puritanism influences everyone. But Franklin was no puritan, and to assume that the beliefs of puritans were the basis for his tips on chastity adds no real insight to this discussion. Anyone can easily identify ideals in our present and past that seem adverse to liberal sexuality and cry "Puritan!"--but this discounts the brilliance of people like Franklin. He had a high level view of the different ideals in his culture and often addressed them with a tongue-in-cheek or satirical tone.

As an aside, neither the Puritans nor mainstream culture in Franklin's era were especially prudish about sexual activity. What people call 'puritanical' today is really an artifact of the Victorian era.
