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 involves the receiving partner being on all fours while the penetrating partner enters from behind. Cowgirl is a position where the receiving partner straddles the penetrating partner and controls the rhythm and depth of penetration. Reverse cowgirl is similar to cowgirl, but the receiving partner faces away from the penetrating partner. 69 is a position where both partners engage in oral sex simultaneously.
