How do you use the Balldo?

The Balldo is a device designed for men to turn their testicles into a penetrative sex organ, promoting an entirely new sexual experience. To use the Balldo, he first puts on the provided BallSling to ensure his scrotal skin is tight. The BallSling helps in preventing the testicles from retracting during arousal. After ensuring they are snugly encased, he then lubricates the inner part of the Balldo and his testicles to ease insertion. He inserts his testicles into the Balldo, which acts like a cage with an insertable end. The Balldo is thus positioned so that the testicles can be used for penetration similarly to a penis. It requires some experimentation to find the most comfortable and pleasurable method of use, as it provides a unique experience based on individual anatomy and sensitivity levels.
