Brad Hart reviews an interesting study of Puritan (and other colonial American) sexuality at American Revolution. I agree that it’s hard to study colonial sexuality when only the most sensational of situations (court cases, executions) were recorded for public posterity, but there’s certainly work to be done combing through the journals and other records we do have.
The image we tend to have of Puritans in New England as sex-haters is completely mythical; see just about all my Truth v. Myth posts on the Puritans for proofs!
