General: cowgirl position
A sexual position where the Top, the person doing the penetrating (whether or not they're actually above their partner), lies down on his or her back, and the Bottom, the person being penetrated (likewise), straddles the Top's body and sits down on the Top's penis or strap-on, facing them. The Bottom must be sitting at least partially upright and not laying down.
In the event the Bottom has their back to the Top, this position becomes the reverse cowgirl position.
Despite the name, the cowgirl position is not gender-specific; images of homosexual males engaging in the position receive the same tag, as there is no "cowboy" position.
