### REPLY:
Some popular sex positions for couples include missionary, doggy style, cowgirl, reverse cowgirl, and spooning. Missionary involves the man being on top and the woman lying on her back, while doggy style involves the woman being on all fours and the man entering from behind. Cowgirl and reverse cowgirl involve the woman being on top, either facing towards or away from the man. Spooning is a position where both partners lie on their sides, with the man entering from behind.
