Can you describe some popular sex positions for couples?

### REPLY:
Sure, some popular sex positions for couples include missionary, doggy style, cowgirl, and 69. Missionary is a classic position where the receiving partner lies on their back, and the penetrating partner is on top. Doggy style involves the receiving partner being on all fours while the penetrating partner enters from behind. Cowgirl is when the receiving partner is on top, allowing for more control and exploration. Lastly, 69 is a position where both partners engage in oral sex simultaneously.
