What is sex position woman laying on belly?

The sex position where a woman lays on her belly is known as "prone bone" or "the flying doggy style". It is a variation of the doggy style position, where the partner penetrates from behind.

In this position, the woman lies flat on her stomach with her arms stretched out in front of her head, while the man straddles her legs and enters from behind. This position allows for deep penetration and can be great for G-spot stimulation. It can also provide some visual stimulation for the man, as he can see his partner's back and bum.

However, this position may not be comfortable for all women, especially those with lower back pain or who feel exposed in this vulnerable position. It is important to communicate with your partner about what feels comfortable and pleasurable for both parties. Additionally, adding pillows or adjusting the angle of entry can make this position more enjoyable.
