What are some popular sex positions?

### REPLY:
Some popular sex positions include missionary, doggy style, cowgirl, reverse cowgirl, and the 69 position. Missionary is when one partner lies on their back while the other partner is on top. Doggy style is when the receiving partner is on all fours while the penetrating partner enters from behind. Cowgirl is when the receiving partner straddles the penetrating partner and controls the movements. Reverse cowgirl is similar to cowgirl, but the receiving partner faces away from the penetrating partner. The 69 position involves both partners orally stimulating each other simultaneously.
