What are some popular sex positions for couples?

### REPLY:
Some popular sex positions for couples include missionary, doggy style, cowgirl, and reverse cowgirl. Missionary involves the man on top and the woman underneath, while doggy style involves the woman on all fours and the man entering from behind. Cowgirl involves the woman on top, straddling the man, and reverse cowgirl is the same position but facing away from the man. These positions can provide different levels of stimulation and intimacy.
