What are some popular sex positions?

### REPLY:
Some popular sex positions include missionary, doggy style, cowgirl, reverse cowgirl, and 69. In the missionary position, the receiving partner lies on their back while the penetrating partner lies on top. Doggy style involves the receiving partner being on all fours while the penetrating partner enters from behind. Cowgirl position involves the receiving partner straddling the penetrating partner and controlling the rhythm and depth of penetration. Reverse cowgirl is a variation of cowgirl where the receiving partner faces away from the penetrating partner. In the 69 position, both partners engage in oral sex simultaneously.
