I have been wanting to get a penis extension with a vibrator at the head. I bought one that looked good, but when I got it out of the box I discovered that I had really wasted $30. It was like a plastic cage for my cock. It only went down half way on my dick, which it seemed to me meant that it would easily fall off when screwing. The vibrator at the end of the thing only turned on when you pushed on it with your cock, which seemed almost impossible to do. Besides my cock head fell through the little holes on the side of the thing, and really, I am not that big (7X6). It was called a vibrating rabbit extension. Wouldn't recommend it. Anybody use it, and figured it out as a helpful thing? Am I missing something?
