Some popular sex positions include missionary, doggy style, cowgirl, and reverse cowgirl. Missionary position involves the man on top, while doggy style involves penetration from behind. Cowgirl position involves the woman on top, and reverse cowgirl is similar but with the woman facing away from the man. These positions can provide different sensations and allow for varying levels of intimacy.
