Over the Hump
How you do it: Start by lying on the bed on your stomach, using a pillow or two to support your stomach and hips. Use your hands or a toy (or both!) between your body and the pillow to rev things up.
Why it's awesome: "The pillows angle your hips up, which opens up new sensations.It also uses the tension of your leg muscles, which can feel very different for you," Katz says.
