What are some popular sex positions for couples?

### REPLY:
Some popular sex positions for couples include missionary position, doggy style, cowgirl/reverse cowgirl, spooning, 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/reverse cowgirl involves one partner straddling the other partner, either facing towards or away from them. Spooning refers to a position where both partners lie on their sides, with the penetrating partner entering from behind. 69 is a position where both partners engage in oral sex simultaneously.
