Can you provide a list of popular sex positions?

### REPLY:
Sure! Some popular sex positions include missionary, doggy style, cowgirl, reverse cowgirl, 69, and the standing position. Missionary involves the partner on top, while doggy style is when the receiving partner is on all fours. Cowgirl is when the receiving partner is on top, facing their partner, and reverse cowgirl is the same but facing away. 69 involves simultaneous oral sex between partners, and the standing position is when one partner is standing and the other is lifted or supported against a surface.
