In this position, you lie face down with your hips slightly elevated so he can enter from behind. 

He lies, face up, with his head and torso off the edge of the bed. Then, you straddle him with your legs dangling or rested in front.  

He stands behind you while you get on your hands and feet. Instead of keeping your feet on the floor, he should lift you from the pelvis while you grip

your legs around his waist. 

He lies on his back with his legs stretched out, and you kneel on top with your legs straddling his hips and your back towards him. 

This position is similar to missionary but with an added twist - you lie on your back with your legs stretched and calves rested on his shoulders.

Both of you lie on your side and face the same direction. Your knees should be up slightly, so he can enter you from behind.

He sits on the bed with his legs stretched out, and you straddle him with your knees up and feet on the bed.

You sit on a chair with your legs wide open, so he can do his thang!

You both stand facing one another. You raise either one of your legs, wrap it around his waist, and pull him inside you.
