What are some popular sex positions?

### REPLY:
Some popular sex positions include missionary, doggy style, cowgirl, reverse cowgirl, and 69. Missionary is the most common position where one partner lies on their back and the other partner lies on top, facing each other. Doggy style is when one partner is on all fours and the other partner penetrates from behind. Cowgirl is when one partner straddles the other and controls the movements. Reverse cowgirl is similar but facing the other way. 69 is a position where both partners give and receive oral pleasure simultaneously.
