What are some popular sex positions for couples?

### REPLY:
Some popular sex positions for couples include missionary, doggy style, cowgirl, reverse cowgirl, and 69. Missionary involves the man being on top of the woman, with her legs spread apart. Doggy style involves the woman being on all fours while the man penetrates from behind. Cowgirl and reverse cowgirl involve the woman being on top, either facing the man or facing away from him. In the 69 position, partners engage in mutual oral sex. It's important for couples to communicate and find the positions that work best for them.
