The Rimba Electro Penis Strap is my favorite. It holds my cock and balls out further away, which both my wife and I enjoy seeing. The sensation/stimulation produced is remarkable. It works great for no hands masturbation. We found that even better was that if there was some rubbing to the head of the penis produces an incredible climax. When I cum, it shoots about 18" further than I normally do. Use an electrode gel and don't start off with maximum power.
