What are some popular sex positions for couples?

### REPLY:
Some popular sex positions for couples include missionary position, doggy style, cowgirl position, reverse cowgirl, and 69. Missionary position is when one partner lies on their back while the other partner lies on top, facing each other. Doggy style is when one partner kneels behind the other partner. Cowgirl position is when one partner straddles the other partner while facing them. Reverse cowgirl is similar to cowgirl position, but the partner is facing away. 69 is a position where both partners engage in oral sex simultaneously.
