In case you missed it: US Patent 9,145,667--Toilet sanitary shield for male genitalia
A toilet sanitary shield for male genitalia comprising: a shield; a securing device; a ball and socket joint; wherein the ball and socket joint are affixed between the shield and the securing device; wherein the securing device is adapted to be secured to a toilet; wherein the shield is adapted to receive male genitalia thereon so as to protect said male genitalia during usage of said toilet.
The securing device 102 comprises a suction cup 107 and a socket portion 108 of the ball and socket joint 103. The suction cup 107 is a curved semi-flexible piece of material. The socket portion 108 of the ball and socket joint 103 is attached directly to the convex side 113 of the suction cup 107. When the concave side 112 of the suction cup 107 is adaptively placed against the toilet 114, and the center of the suction cup 107 is pushed to the toilet 114, the air (or water depending on placement) is expelled from the space between the toilet 114 wall and the concave side 112 of the suction cup 107. As the suction cup 107 tries to recover to its original shape, a negative pressure is formed in the space between the toilet 114 wall and the concave side 112 of the suction cup 107. The positive pressure of the air (or water depending on placement) pushes against the convex side 113 of the suction cup 107 holding the securing device 102 in place. Suction cups are well known in the art.

The Big Boys Cave has a Big Boys Rest to position the penis horizontally. This horizontal position avoids the penis from dropping into the toilet thus preventing men from picking up germs on their penis from the waste in the toilet.
