I had a few misgivings ahead of time. Number one is, why wouldn’t you just use a pillow to do what the Liberator does? I learned immediately upon receiving the Wedge that it’s not that simple, since the Liberator is made of this heavy duty foam material that’s way sturdier than a pillow but just pliant enough to be comfortable. Welcome to sex in the 21st Century! None of my fluffy pillows could possibly compete with this firm foam.
