The missionary position or man-on-top position is generally a sex position in which a woman lies on her back and a man lies on top of her while they face each other and engage in sexual intercourse or other sexual activity. Though commonly associated with heterosexual sexual activity, the sex position is also used by gay and lesbian couples.
When the missionary position is used by a lesbian couple, each woman will take a turn at lying on top.
