What are some popular sex positions for couples?

### REPLY:
Popular sex positions for couples include missionary, doggy style, cowgirl/reverse cowgirl, spooning, and 69. Missionary involves the man on top and the woman lying on her back. Doggy style is when the woman is on all fours, and the man penetrates her from behind. Cowgirl/reverse cowgirl involves the woman being on top and in control of the movements. Spooning is a position where both partners lie on their sides, facing the same direction, with the man penetrating from behind. 69 is a position where both partners engage in oral sex simultaneously.
