The anvil sex position is executed by having the woman lays flat on her back with the man on top. She then brings both of her legs close to her chest and rests her calves on the man’s shoulder. This position is easily achieved when the lovers are performing a missionary sex position since it is easier to transition to the anvil position.
This position allows for much deeper penetration, especially when the woman absolutely likes to be filled completely. It is also a position when the ultimate stimulation of the clitoris happens.
In the anvil position, the man performs a back and forth movement that does not necessarily imply thrusting in and out of the woman’s vagina. It is more of a rubbing movement that is greatly stimulating. And the woman can also take control by using her legs to push the man to dictate the depth of penetration.
