What are some popular sex positions?

### REPLY:
Some popular sex positions include missionary, doggy style, cowgirl, reverse cowgirl, and 69. Missionary is a position where one partner lies on their back while the other partner lies on top, facing each other. Doggy style is a position where one partner is on all fours while the other partner penetrates from behind. Cowgirl is a position where one partner straddles the other partner and controls the movement. Reverse cowgirl is similar to cowgirl, but the facing direction is reversed. 69 is a position where both partners perform oral sex on each other simultaneously.
