The Feeldoe is a unique and patented toy. Its strapless strap-on is designed to give skin-on-skin contact without breaking continuity of action to adjust straps and buckles. It works! A woman uses her PC muscles to hold it in place with the bulb as the shaft protrudes at a natural angle. The Feeldoe Slim is easier to hold and control than the original, and the Slim is 10% lighter than the original model, making it lighter for the driver. The design is also harness compatible.
