There are several popular sex positions for couples, including missionary, doggy style, cowgirl, and spooning. Missionary position involves the man on top, while doggy style involves the woman on all fours. Cowgirl position allows the woman to be on top, and spooning is a position where both partners lie on their sides, facing the same direction, with the man positioned behind the woman.
