"How Cute. A Puritan Couple."
There is a belief that Puritans were either against or above relationships. It may be because of the cases of punishment over events all tying to relationships, such as the plot of Nathaniel Hawthorne's The Scarlet Letter. Puritans did believe in relationships, and even furthermore, sexual relationships. Puritans held sexual relationships in high regard to their marriage, contrasting that idea them being sexually restricted. There's no better way to explain the average Puritan family having six children.
