It's a strapless strap-on designed to give skin-on-skin contact without breaking the continuity of action to adjust straps and buckles. It works, by using your internal muscles to hold it in place with the bulb as the shaft protrudes at a natural angle. Wearing the Tantus Strapless is a very different strap-on experience. We recommend you wear it around the house, getting used to your new center of gravity, how it moves and how you can control the movement before you try it with your partner.
