A disk shaped device made of surgical rubber that prevents unwanted tissue from being drawn into the penile cylinder and helps create the proper 'Air Tight' seal without having to trim pubic hair or use as much sealing gel. This disk is very pliable and can easily be removed once the erection is created and the Support Ring is in place.

This has been an effective solution to a problem I have had ... guess others did, too. Removal, once the ring is in place, remains a bit of a challenge but can be done. I think the shield is an essential piece of the apparatus and probable should be standard equipment.
