What are some popular sex positions?

### REPLY:
Some popular sex positions include missionary, doggy style, cowgirl, reverse cowgirl, 69, and anal. Missionary position is when one partner lies on their back while the other partner is on top. Doggy style is when one partner is on all fours while the other partner penetrates from behind. Cowgirl position is when one partner straddles the other partner and controls the penetration. Reverse cowgirl is similar to cowgirl, but facing the other way. 69 position involves both partners engaging in oral sex simultaneously. Anal sex is when penetration occurs in the anus instead of the vagina or mouth.
