Putting a Vac-U-Lock dildo into a harness is important for penetrative fun. The harness, which is the foundation or base for the strap-on, is the point of attachment for the dildo, and it fits both men and women. One partner wears the harness, and it is adjustable by the straps. To mount a Vac-U-Lock dildo into a harness, attach/dildo with one hand on the harness adapter plug while holding the other hand.
The adapter plug and attachment are designed to have a tight fit that will prevent the attachment from rotating on the plug during sexual intercourse. The first step in putting a Vac-U-Lock dildo into a harness is to ensure the harness and dildo are compatible.
