There are numerous popular sex positions for couples, including missionary, doggy style, cowgirl, reverse cowgirl, spooning, and 69. Missionary is a common position where the receiving partner lies on their back while the penetrating partner lies on top. Doggy style involves the receiving partner being on all fours while the penetrating partner enters from behind. Cowgirl and reverse cowgirl involve the receiving partner straddling the penetrating partner and controlling the movement. Spooning is a position where both partners lie on their sides, with the penetrating partner entering from behind. Lastly, 69 involves both partners engaging in oral sex simultaneously.
