What are some popular sex positions for couples?

### REPLY:
Some popular sex positions for couples include missionary, doggy style, cowgirl, reverse cowgirl, and 69. In the missionary position, one partner lies on their back while the other partner lies on top, facing each other. Doggy style involves one partner being on all fours while the other partner penetrates from behind. Cowgirl involves the receiving partner straddling the penetrating partner while facing them. Reverse cowgirl is similar to cowgirl but with the receiving partner facing away from the penetrating partner. Lastly, 69 involves both partners simultaneously performing oral sex on each other.
