What are some popular sex positions?

### REPLY:
Some popular sex positions include missionary, doggy style, cowgirl, reverse cowgirl, and the 69 position. Missionary involves one partner lying on their back while the other partner lies on top of them, facing each other. Doggy style involves one partner on all fours while the other partner penetrates from behind. Cowgirl is when the receiving partner straddles the penetrating partner and controls the rhythm and depth of penetration. Reverse cowgirl is similar to cowgirl, but the receiving partner faces away from the penetrating partner. The 69 position involves simultaneous oral-genital stimulation between partners.
