Here’s a solution which works, especially if you like to mix your V2000 with rubber; I have latex pants that have a penis ring built in. With the pants off stretch the ring over the bottom end of the receiver and then lubricate the inside of the receiver and put the pants on. Connect everything up and away you go. The pants will hold the receiver in place. For a very snug fit use close fitting pants, for a bit more movement use oversize pants. Another variation on this theme is to use pants with a penis sheath built in. Cut the tip off of the sheath and stretch the sheath over the end of the receiver. This allows a good amount of movement of the receiver but still holds it in place.
