It is commonly believed that the term "missionary position" arose in connection with English-speaking Christian missionaries, who supposedly encouraged the sexual position in new converts in the colonial era. However, the term probably originated from Alfred Kinsey's "Sexual Behavior in the Human Male" through a confluence of misunderstandings and misinterpretations of historical documents. The French refer to it as the 'classical' position. Tuscans refer to the position as "the Angelic position" while some Arabic-speaking groups call it "the manner of serpents."
