What are the most popular sex positions?

### REPLY:
Some popular sex positions include missionary, doggy style, cowgirl, reverse cowgirl, and 69. Missionary is a position where the receiving partner lies on their back with their legs spread while the penetrating partner is on top. 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 is on top, facing the penetrating partner. Reverse cowgirl is similar to cowgirl, but the receiving partner faces away. 69 is a position where both partners engage in simultaneous oral sex.
