Can you describe some popular sex positions?

### REPLY:
Sure! Some popular sex positions include missionary, doggy style, cowgirl, and 69. Missionary is a position where one partner lies on their back while the other partner lies on top. Doggy style involves one partner being on all fours while the other penetrates from behind. Cowgirl is when the penetrating partner lies down while the receiving partner straddles on top. Lastly, 69 is a position where both partners engage in simultaneous oral sex. It's important to communicate and find positions that are comfortable and pleasurable for both partners.
