Citation? The Puritans thought sex was a wonderful thing within Christian marriage, and on at least one occasion excommunicated a man for neglecting his wife sexually, based on the Biblical command that a husband's body belongs to his wife and vice versa. Contrast this with Catholics, who still require celibacy of priests in 2016, and who imagine the Virgin Mary remaining a virgin her whole life, despite being married, because this, in their view, is part of her holiness.

Who also think sex is a wonderful thing within Christian marriage.

"Celibacy" means "not being married", requiring priests to be celibate (which, strictly speaking, Catholics do not [0]) is orthogonal to beliefs about whether sex is wonderful within Christian marriage.
[0] The Catholic Church does not permit priests to marry, but does not bar married men from ordination to the priesthood (it does bar married men from ordination to the episcopate, however.) The Latin Rite of the Catholic Church has a particular discipline which requires that only unmarried men may be ordained to the priesthood, a discipline that was adopted to deal with particular disciplinary problems that arose during the Middle Ages, but which has never been held to be theologically necessary (and which isn't applied within the Church outside of the Latin Rite.)
I've been curious how much impact they have had on our current culture; a people who (to paraphrase Robin Williams) were so uptight they got kicked out of England.
Christian mores definitely still drive our cultural mores, and while there is some easing of the restrictions there, sex is still much less acceptable than violence. As a simple example of this, attempts to reduce the violence in highschool football are as vehemently opposed as attempts to provide more than "abstinence only" sex-ed.
