The term "missionary position" has been used since the 17th century to refer to a sexual position in which a man and woman engage in intercourse while the man lies on top of the woman. However, there are many other words and phrases that can be used to describe this position. Some examples include "man on top," "traditional position," "face-to-face," "conventional position," and "standard position." Regardless of what it's called, the important thing is that both partners feel comfortable and enjoy the experience. It's always important to communicate with your partner and find the position that works best for both of you.
