What are some popular sex positions for couples?

### REPLY:
Some popular sex positions for couples include missionary, doggy style, cowgirl, reverse cowgirl, and 69. Missionary position involves the man being on top of the woman, with both facing each other. Doggy style is when the woman is on all fours and the man penetrates from behind. Cowgirl position has the woman on top, allowing her to control the pace and depth of penetration. Reverse cowgirl is similar to cowgirl, but the woman faces away from the man. Lastly, 69 position involves simultaneous oral sex between partners.
