“First, this needs a semi-rigid shell and a vent hole at the tip to let air out. I am not huge, but getting all the air out was a challenge. The coils add rigidity, but not much else for me. As a more durable inner sleeve for a small tube style stroker, with a way to create and modulate suction, this might work.”
