It hurts (but not in a good way)

So, it looks like the picture and works as described. I really like the sensation as it is tightened down and my wife loves my reactions and that she can see whats going on. BUT, the plexi has sharp edges and they hurt at the insertion points. I know that's kind of a crazy thing to say about a CBT device, but it gets irritating after a while and we stop sooner than we might have otherwise.
